I (M 22) live with my gf (F 21) we have been together for 18 months. Mostly every morning or every other morning she tries to have sex with me and I just don’t want to engage. She is absolutely beautiful and I do find her sexually attractive but sex to me is just a job. It doesn’t feel worth it to me. I have been having sex with her since we first started getting together. Maybe 3-4 times a week while I’m home. (I’m only home half the year due to my work. I’m home 2-4 weeks at a time before returning to work for a month.)

I have expressed that my sex drive is not very active due to being a heavier kid growing up. Sex never really interested me due to my physical appearance. Most of the time when we have had sex in our relationship I have been pretending to “finish” to make it seem like I was interested into the sexual act. She turns me on and I find her stunning I just don’t have the sex drive she’s looking for.

We have talked about opening the relationship and that is not an option we are looking to have. I do really love this girl and she means the world to me. I have thought about kids, family, a place for us, and my entire future with her. I just don’t want to have sex all the time. So in reality, AITA?
