I've been seeing my girlfriend for almost 2 years now and since the end of last year, our sex life has gone downhill. I don't know what to do... I have only cumed twice this whole year and i'm 23. It starts off ok, but then i get bored and go limp. We don't experiment much and we don't have oral sex. I don't really mind because i respect her and she doesn't want to do that stuff... But i've found that i'm looking at porn more now than ever. I have no problem climaxing then, but with my woman, i just can't go all the way. It's affecting my mental state too. I'm getting insecure and that's not helping the situation. I start having sex and now i'm putting pressure on myself, constantly telling myself not to be a 'let down'. I do love her, but i think i'm bored. Furthermore, it's making me not want to have sex. I have spoken about it with her, but nothing has changed. What can i do? I really don't like feeling insecure.
