yo guys, 16 soon 17 year old male

I think i have hocd and it's getting extremely stressful. I have had quite a few sexual encounters with women, none leading to sex, but all going somehwere. I have enjoyed these quite alot.

about 3 monthes ago these sudden gay thoughts started to go into my head, i dealt with them at first, ignoring them, was quite easy; although about a week ago I thought I was gonna have a panic attack, i got soooo bad, i keep thinking bout "am i gay?" in my head, kept regularly testing if i am. Before this point 3 monthes ago, i have had no gay thoughts really. Its really messing with my mind. After the first bad stint, I had a day of hardly any thoughts, no panicing, really nice; even cracked one out to some lesbian porn. this day I was looking forward to my future and really happy; i want a girlfriend and a wife and kids some day, but this hocd is making the vision go further and further away

I think one of the things that's making it worse, is that when I was with some sexual encounters I actually lost an erection, one time after like an hour or so of foreplay (dont ask) and another for some odd reason; during both of these I was shaking horrifically, which i think was nerves.

these voices just torment me man, like "I keep thinking would I like to be with a man" I never come to the conclusion of yes, but it keeps making me think. I think sometimes I have thought way too much, got stressed and started to believe some of the stuff myself.

the hocd symptoms seemed to match with me directly.

I sometimes get this mental block, when trying to wank when im kinda stressed, this normal?

do you think its being gay/bi or hocd?
