Soror, this is too much. I was just in the exact same situation!!! Hopefully, it's not the same guy

! Where do you live again??? But seriously, I know what you're going through. The guy I was dating was very masculine in some ways, but in others, he had a sista worrying. Luckily, we were watching a show together one night that was dealing with homo/bisexuality and I straight up asked him. He very nonchalantly said no, but I still don't know. I've seen or heard nothing to confirm my suspicions, but some of his mannerisms and speech patterns had me wondering. Not to mention that he was very fashion conscience. Not just your typical brotha that likes to look good. He wore the type of stuff that only celebrities would dare to wear.
Anyway, I say all that to say don't sleep on your intuition. Especially if you plan on having a sexual relationship with this man. It's scary enough to think your man may be cheating with another woman, but when you have to worry about the fellas too... After about 2 months, I decided that I just wasn't comfortable with the situation anymore and I ended it. Not only because of my questions about his sexuality, but because he wanted a whole lot more than I was willing to give. If you live in a small community, ask around about him. If you have these suspicions, I'm sure you're not the first.
