"The fact that the man has been with another man at any point is gross."
This statement clearly points to sexual orientation bias. The usual precursor to this sentence is “I don’t have a problem with gay people but…” or “That’s fine for them, but for me…” Why else would you find it “gross” if you honestly don’t have a problem with homosexuality? What’s “gross” about same-sex interaction? Is it the anal sex aspect? For those women who say "yes," I highly doubt they ask every man they date if he has ever had anal sex with another woman. The cooties they’re so afraid of double for the men who have anal and vaginal intercourse with a female partner, which many have. Some come out of one cave, go in another, and back again. I find the “gross” argument especially irritating if it’s coming from a woman who’s engaged in casual sex, has had multiple sexual partners, or dates a man who’s had multiple sexual partners. It’s not gross that the man you’re dating has stuck his gun in multiple holsters, or that you’ve been stuck a couple of thousand times yourself, but a bisexual man is gross simply because he’s been with another man? Oh, ok. That’s not contradictory at all.
"I like a ‘manly man.’ A guy is a less of a man to me if he’s been with another dude."
Cue traditional gender ideals and more orientation bias. It’s been a long held-belief that all gay and bisexual men are effeminate (which isn’t true) and that same-sex interaction is somehow less masculine. Gender ideals come into play as masculinity is partially defined by a commanding presence and sexual prowess/domination. In heterosexual relationships, the man is expected to have a dominant role, while the woman is subordinate. In heterosexual sex, women are automatically in a submissive position as they biologically cannot penetrate and can only be penetrated. Considering those factors, if a man is ever penetrated or allows himself to be, the attitude is that he has taken on a submissive, lesser position and is more like a woman. This attitude is part of the reason why male sexual abuse victims rarely report incidents, particularly if the perpetrator is also male. These victims are made to feel that they are now weak, less-than and automatically homosexual, which is undesirable. Orientation bias is in play as a man’s value is reduced just because of same-sex relations.
Your competition rate is the same. Logically, you’re thinking if you date a straight man, you only have to watch half the room, but imagine if most of the room was female. It’s just like if your man worked at an office with mostly women. Whether your man is straight or bisexual, anyone at anytime can vie for him. It doesn’t matter how many men or women are attracted to him. What matters is if he gives into them or not. If he wants to cheat, he’s going to cheat, no matter who you think you’re watching. The likelihood of someone being unfaithful does not increase or decrease based on sexual orientation. Furthermore, you shouldn’t have to “compete” to keep your man’s loyalty in general.
"I’m afraid I’ll get HIV or AIDS."
No matter who you have sex with, you need to be using protection and getting tested regularly. You can contract HIV, AIDS or any other sexually transmitted disease (STD) from ANYONE. Bisexual men are NOT more likely to carry the illness than heterosexual men. That is a MYTH.
"I’m afraid I won’t be able to satisfy a bisexual man in the bedroom."
Bisexual men enjoy sex with women; that’s why they’re bisexual. No need to worry about those who prefer sex with men, because they’re not going to date you. If you’re concerned about his itch for dick, there’s always dildos, strap-ons and other sexual toys. There’s also dating bisexual men who primarily prefer women sexually. In any case, it’s important to have an open and honest conversation with your partner about desires and concerns. You might find that you won’t have any problems at all. On another, semi-related note, it seems that straight men are a lot less concerned about satisfying their bisexual female mates, than women are about bisexual male mates. That’s likely because of gender politics too. Women are born and raised in a culture that fosters insecurity and low confidence, but that’s a different topic for another day.
Believe it or not, there are some.
For the women who like a balance of control in the bedroom or little adventure, a bisexual man might be up their alley. Because of their varied sexual preference with gender, bisexual men have an easier time sharing control and are more open to trying to new things.
Due to the amount of gender politics and issues that affect a bisexual man’s dating life, these men are sometimes more sensitive to and understanding of the plight of women and gender-based double standards. Those who seek out a more egalitarian dating or home life might benefit from having a bisexual man as a partner.
Think twice before you turn down a man who offers everything you’re looking for just because he’s bisexual. Analyze why you are reluctant to date a bisexual man. Are those reasons inherently and unfairly prejudiced? The mistreatment and dismissal of bisexual men has led some to conceal their orientation from female partners. Not to condone the dishonesty, because I don’t, but I understand why they would consider it.
