This is not at all true. Having a man and a woman make love to me at the same time is one of my fondest memories and pastimes.
I’d think some bisexuals would be more likely to cheat than someone who is only attracted to one gender because they desire sex acts that can’t be performed by their mate - for some people a strap-on just can’t quite cut it. As a straight man, if I’m horny I’m horny, my wife can take care of that. What would I do if I occasionally had the urge to have a dick in my ass?
I agree that there is something to what Sterra said about bisexuals (or at least some) not being attracted to both sexes at the same time. The bisexual friend I talked about in my earlier post leaned more towards wanting women than men, but occasionally (and it seemed fairly regular) she wanted sex with a man. Me and her girlfriend had a common friend (who is the one who told me about the deception going on) and told me that the girl I screwed’s girlfriend didn’t mind THAT much that she was screwing me on the side, but bitched about the girl’s ‘Post-Coital Thing’ (her term) which was a personality shift she seemed to have after she had had sex with me, she said she would act more feminine and bitchy yet less aggressive sexually for a few days.
Well, what if you like both large and small breasted women, and you marry a small breasted woman. What do you do if you occasionally have the urge to have your face smothered in giant mammaries? You just deal with it. You made your choice, and that’s that. Heck, if you want rectal dicking at least your wife could partially oblige you with a strap-on. No such luck for giant breast fetishists.
I dated a woman who was self-proclaimed bi. She’d been with men, but never with a woman, and she really wanted to date this one woman. We weren’t dating seriously, so I was encouraging her to act on her desires. But she was really worried, because her woman of choice was lesbian rather than bi, and there was concern of “bi-phobia.” That was a new one to me…I’d heard of homophobia, but bi-phobia? I’d sort of figured that gay folks would be a little more open-minded, but apparently I was wrong. I guess you can be prejudiced regardless of your orientation. Wacky.
