People are misunderstanding and over complicating the sex thing.
It has never been my experience of gay men, and I have known many to be physically repulsed by a woman’s body.
Gay men can appreciate women’s bodies, find them attractive and be comfortable around women without being sexually attracted to them.
I used to work in the glamour modelling industry, it was the gay stylists and makeup artists who were often unnecessarily grooming and applying products to women’s naked bodies. Although it probably wasn’t turning them on they were all very comfortable and enjoyed the experience, it was just fun.
I would say that it’s the ‘straight’ men/women who claim they would be physically sick if they saw another man/woman naked who are not at all comfortable or confident in their own sexuality and probably aren’t as straight as they want to believe.
I am not physically repulsed by other women’s bodies, I have lots of close female friends who I am comfortable being naked around. I mildly experimented with women in my teens, I don’t believe I am bi or have sexual attraction towards women, it was just fun. I can imagine a mutually beneficial situation where with a woman I am very comfortable with I could feel physical pleasure from and be happy to give physical pleasure to.
If that makes us both Bi in your eyes then so be it, but that is not how we Identify.
