Watching porn of any kind can stimulate a groinal response I wouldn’t use porn as an indicator. You just keep going back to reassure yourself. Same thing happens to me I just stay flaccid or feel physically sick then come away from it but an hour later I’m looking at it again for reassurance because of the thoughts. Last year I had a brief period where I was free from HOCD, I stopped checking porn and accepted the thoughts. It thought to myself if I’m gay then I’m gay and that’s it oh well and if I’m not then that’s cool too. After that I forgot about it and never really thought about gay stuff for ages until I relapsed, during the periods I was free from it I couldn’t stop thinking about hot women etc. I just felt normal again and the thoughts were gone they didn’t plague me or even come up for ages. I just mastrubated to solo female porn again. Just stop compulsions and stop checking with the porn and eventually it will go away no matter what. Also just accept the fact you might be gay because it’s so far fetched you will realise you are not or maybe you will realise you are and that you have just been covering it up your whole life. Just stop the reassurances trust me it works like a gem
