My gf gets tired very soon during sex. We've been in a relationship for past 3 years. We've been having sex for past 2 years and everytime she gets tired so soon. Sometimes, I don't even get to finish myself. I'm understanding but it sometimes gets to me. I love her very much and we're in a really good spot in our relationship. I just want to help her. I wish there was something we could do to help both of us together. Please help me.

All this makes me feel unsatisfied. I don't want to jerk off and get off that way becauseId feel that would become a habit. Earlier I used to jerk off everyday. I started nofap and I thought that would make things better but her not letting me finish has made me think of giving up my nofap. But I don't want to. P. S She ain't fat or chubby. She's got an average figure.
