I could only get horny with my girlfriend.
Hello. I’m 23 years old and I've always been a horny guy. I've been with this girl for 3 years I was her first and I don't know maybe because she made me wait for it for almost 2 years I developed feelings for her.
Now I only have to be around her and my penis would be as hard as it could get. The sex is great I mean I could go for hours with her I could have an orgasm and still keep going until she tells me to stop. The problem I'm having is that with any other girl I can't get hard, is like I don’t even be horny. I want to know what’s happening to me. I mean is very embarrassing when you're trying to do someone and your thing doesn't get hard. Please help me understand what’s happening to me and if anyone has a solution please share it with me please.
