It would depend on what the lesbians looked like, but I'd defintely be up for making a pass at them. You never know, they may be interested in taking a trip on the wild side.
It is obvious that you are projecting your own sexual perversions on Michael Sam. The fact that you think it would be appropriate to make passes at a woman (especially one you know is a lesbian) in a non-sexual situation, such as showering after an athletic event, is sick. If what you call "normal" is opportunistically attempting sex with every female, then I can only hope there are few "normals" around. I can only hope your contact with females is limited to situations in which there are people present to stop you from assaulting them.
Calm down please. No one is talking about assaulting anyone. When I say I might be up for making a "pass" at someone, it would be based on the feeling I get from the person. If they are into flirting, and there appears to be a connection, then I might make an advance. If they are completely uninterested, I would back off immediately.
Keep in mind, just because a woman say's she is a lesbian, doesn't mean she wouldn't be interested in exploring. Again, it would depend on whether there was a connection or not.
Years ago, I had a conversation with a woman who claimed to be a lesbian, and who also claimed to be in a long-term committed relationship with her partner.
But, she said a couple times a year, she would have a " hankering", as she put it, for a man.
She would hang out in a bar for a couple days, and manage to find someone who was more than willing to oblige her. She was fairly attractive, and defintely feminine, and I also would have been quite happy to entertain her for the evening.
You really come off as a stuffed shirt.
