Lover Sexuality Preference
Lesbians (but not gay men) strongly prefer monosexuals over bisexuals; similarly, straight women have a narrower range of desire for men than straight men have for women.
Sexual Orientation Preference (or Partner Sexuality Preference)
Did you date because — or discover later?
I often get this question when discussing how I’ve mostly dated bisexual women since I was 17 years old (half of my existence & nearly half of my life).
To be clear, I never dated anyone because they were bisexual, but given previous successful relationships (despite none leading to marriage yet), a romantic auditor may consider it a plus according to research by Garelick et al. (2017) (see below). In most cases I didn’t know she was bisexual until months (or, in one case, years) after we were Facebook Official.
Given the significantly lower amount of bisexual women relative to heterosexual women in the world, the fact that more than a supermajority of women I’ve dated have been bisexual (even if only counting Facebook Official girlfriends) suggests that it’s something about me. Indeed, the ‘Taylor Swift Rule’ could be discarded into ancient folklore at this point as the odds of my dating history are far lower than hers. And her romance of 4+ years is longer than my longest with a lover at 3.5 years. Style.
Taylor Swift Rule
Research by Park & McDonald (2019) finds evidence of what is colloquially known as the Taylor Swift Rule: Individuals tend to be drawn into relationships with a particular type of person, just like as introverts are drawn to Barnes & Noble & extraverts are drawn to Coachella. Basically, if you date multiple people over time & experience similar outcomes, at some point it’s you.
Think about a bff who always seems to fall for women/men who end up cheating on them. And no matter how many red flags you see early on, those flags look pink to your friend because they still have their rose-colored glasses on.
Rose colored glasses diminish one’s capacity to accurately perceive red flags.
Despite your best efforts, your friend ends up dating someone like that again, just like an introvert randomly waking up to discover they fell asleep inside Barnes & Noble.
It is noteworthy that Taylor, whose regency is second only to Queen Beyoncé, has clearly figured things out as she’s been with Joe for over 4 years. I don’t have any bad blood with her — simply defining the phrase.
It’d be more apropos to call it the Justin Bieber Rule at this point. Sorry, sorry, not sorry.
My propensity for dating bisexuals hardly arises out of a Blank Space. Though I’ll refrain from discussing any personal romantic preferences here, the following passage is instructive 💁🏻
Garelick et al. (2017): People in InterOrientation relationships tend to show more awareness of & willingness to discuss the role of gender in a relationship & gendered behaviors compared to MonoOrientation opposite-sex relationships, which may affect common relational conflict issues such as division of household labor, which may in turn affect relationship satisfaction. Look what you made me do.

Lesbians’ Lover Sexuality Preference
Lesbians have a strong partner sexuality preference for lesbians over bisexual women (Rust, 1993), as they don’t feel bisexual women will be as committed to long-term relationships with someone of the same-sex (Eliason, 2001; Steinman, 2001). As such, they may pressure bisexual partners to overcompensate/prove their loyalty within a same-sex relationship in a way that isn’t true for lesbian-lesbian, gay-gay, bisexual-bisexual, or bisexual-heterosexual couples (Gonzalez et al., 2017; Israel, 2018; Stein, 2020).
Bisexual mothers in particular often felt that lesbian communities were exclusive or unwelcoming to them (Bartelt et al., 2017; Kangasvuo, 2011; Manley et al., 2018; Ross et al., 2012).
Gonzalez et al., 2017: “Bisexuals are often perceived as sexually promiscuous (Alarie & Gaudet, 2013) & not seen as suitable partners for heterosexual or LG individuals (Breno & Galupo, 2008).”
Lesbians’ beliefs about bisexual promiscuity are ironic given that bisexual women are far more likely to cheat on boyfriends than girlfriends (Hoang et al., 2011).
Hoang et al. (2011) → “Bisexual women had a higher rate of infidelity with their boyfriends (62.5%) than girlfriends (10.5%), regardless of whether the affairs were with men or with women.”
Bisexual ≠ Lesbian
It is important to investigate the preferences of bisexual women & lesbians separately “because bisexuality does appear to be a meaningful category apart from homosexuality (Loewenstein, 1985)” (Cohen & Tannenbaum, 2001). Combining bisexuals with lesbians makes as much sense as combining them with heterosexuals. Bisexuals aren’t monosexuals.

Bisexual Men ‘s Infidelity Concerns When Dating Women vs. Men
Whether a bisexual guy is more concerned with sexual or emotional infidelity depends on whether he’s dating a man or a woman.
“Men tend to worry about sexual infidelity, because they want to know that their female partners’ children are their own, and women tend to worry about emotional infidelity, stemming from a time when they had to worry about men allocating resources to their relationship.
Under this theory, it makes sense that bisexual men dating women would be more worried about sexual infidelity than bisexual men dating men, who can’t get pregnant.”
HOWEVER → “A post hoc comparison between women dating women and women dating men was conducted on the proportion of women who chose emotional infidelity as more distressing and was found to be nonsignificant.”
Bisexual Men Dating Men → Participants in a same-sex relationship showed no sex difference (M-M = W-W on sexual infidelity concerns).
Bisexual Men Dating Women → For participants in an opposite sex relationship, the traditional sex difference emerged: bisexual men cared more about sexual infidelity than bisexual women (Scherer et al., 2013).

Who is most open to dating bisexuals?
Straight men are more open to dating bisexual women than straight women are to dating bisexual men, but the second poll suggests that romantic openness may not indicate that straight men are bi allies. Indeed, most votes leaned towards the notion that straight men would be less interested in dating a straight woman if she previously dated a bisexual male. Moreover, most voted that bisexual men would be least likely to lose their virginity to someone of the same-sex.
