I consider myself heteroflexible. I'm not attracted to guys or even hit on them. I only have sex with women and fap to that. However, I think penises are attractive. I'll fantasize of slobbing some knob at random times but I have no interest in gay sex even if I was a top. Making out with guys doesn't feel right.
I've wanted to try oral on a guy (again) but I'm ultra-paranoid that word will get back in my social circle to make my life a living hell (thanks, experimental years). Recently, in a sex positive place I was in, where I knew no one, an opportunity made itself available where I could give a guy head. I didn't hesitate. I slobber for a bit on a big dick (8+) as it just felt right. I didnt try to get him to cum as I just wanted the taste and feel.
How I felt afterward? I just said to myself, "That's cool. Glad I tried that again." I just kept it to myself. I didn't feel like I was suddenly gonna go gay as I knew I still lusted after women. Just let your fears go and do what feels right if given a chance.
