Sounds like you are very confused right now? Step back from it for awhile...Take your time. Having thoughts of guys while watchig porn sounds like an indication that u may be gay? Quote: you said "i guess suddenly that the lower region suddenly looks strange to me" that of a female while masturbating.

I think u need to really slow down and give yourself times to process all of this. Get a good therapist and take it from there.

Good luck
