HOCD? DENIAL? *graphic*

Ok, so several months ago I got fairly baked and weed makes me really horny sometimes so I was getting ready to do the deed and I decided to look up porn in a female point of view because I was curious and I found it incredibly arousing at the time. Once I finished panic set in and was like "That was kind of gay, am I gay?" I cannot remember if I got off to that kind of thought before which also sucks, but now I'm having a terrible time even getting off to straight stuff anymore and I don't know what is wrong. I used to have thoughts of getting married and having children and all that, but now I'm so worried that I was living a lie and I've been gay from the beginning
