I seriously think I have a drug problem. However, the problem is that I need it to enjoy sex with my girlfriend. I smoke weed often, and it gives me the best feeling in the world, but when I come down, I'm not really interested in anything. I can have sex with her while I'm not high, but I really don't enjoy it as much. I really don't enjoy it at all. I would much rather be high and she is starting to notice and questioned me about it. I don't know what to tell her.
This may prove to be a serious problem and will eventually become fully obvious to your partner. The fact that you are only interested in intercourse with your girlfriend when you are in an altered state should make you want to step back and seek some sort of help. First thing you need to do is put the drugs down. Once you conquer that, seek things that pleasure you and involve her in it. This is just a mental thing. Maybe you haven't experienced different scenarios or fantasies because you were too busy being high. There is a whole world out there without being under the influence. Come join us. Your relationship may very well depend on it.
