Hey, I'm 27M and in a relationship with my partner from past 4 years.

Our sex life started on a rocky note (for me) as I was a virgin at that time and she was active sexually before with her ex. As a virgin, I failed miserably during the initial few times when we tried to have sex and it kind of left me in a state of inferiority (not comparing with her ex but just thinking that I'm not able to satisfy her) due to which I never used to initiate or try to avoid with excuses (because we do it and I don't last long and it leads to a fight).

Later consulting doctors and all it got to a moderate stage where I used to do okay and was able to make her orgasm in PIV (sometimes) and others ways. But the drive was not really there inside me cause somewhere I am still on the back foot/inferiority I guess.

Nowadays I do it because I have to otherwise it might cause fights, but I never feel the excitement, joy or pleasure.

Any suggestions on how to get out of this phase and be a normal person who craves for & enjoy sex?
