I'm a 20 year old female and also gay.
And for a few years now, I always find myself thinking about sex like all the time, I know it doesn't sound like a big deal, but it is ridicuilous how much I do think about it and how often I get turned on, and no matter how many times I have sex, I'm still just as turned on the next day, and I had tried masterbating often and still the same problem, its like consuming my every thought!! What do you think it is?? Or what can I do to make it stop??

You may have an addiction. I would start to think a little deeper about your past and try to understand why you crave it-is it for comfort/protection, a feeling of safety? When did this start? There may be a moment when you can say that was the exact point when it started to occur.

At the same time though, you may just have a high sex urge-as "all the time" might not mean literally all the time..

Maybe your not getting what you want from the sex your getting. I'm not gay but I do know if you don't get what you want from sex,mastrubation, or any of that your going to end up going right back to it the next day. Try to find the "satifying sex"

The problem lies in not being sincere to our so called desire to get out of it. Still you like it - but you are unable to stop it. Make your desire - to be out of it - whole heartedlly. The mind when it REALLY wishes to do a thing shall do it. Be serious about what you say. There the matter ends.

Sounds like you are in a sexual rapture of some kind. The only way to break the all-consuming nature of it is to stop all sexual acts for a couple of weeks. You will need to have other things ready to do when the urge comes on you... exercise, hobbies.

Distract yourself. :)

Maybe your sex is as satisfying as you want it to be, subconsciously you are not achieving the ulitimate sex your looking for.
