I just think society likes to place guys in a box or label them, and at the same time judge them for having sex with other guys so a lot of them lie about it or keep it a secret. Some guys really just like getting penetrated from time to time. I've been having sex with this one guy for over 3 years, who's divorced with two kids, and sleeps with women, men and trans. He doesn't want any emotional connection to a man though (neither do I tbh) and we've never even kissed. He always wants to watch trans porn when he comes over and just get fucked. That's it. There's a lot of guys out there who are like that and he doesn't really fit into any label from what I can see.
