My partner and I have been together for a year and a half, living together for almost a year. We've had minor issues here and there mostly with my communication but we are both working on ourselves and everything is going really well right now.

So ill start with we are both fairly conventionally attractive. We also look very similar, have similar styles, and have similar body types. Hes a couple inches taller a lankier, and im just a bit stockier, we weight almost exactly the same though.

He finished school for now and started his first job a few months ago and has been getting leaner and stronger over the past few months. I used to work the same job as him and its a bit physical but not much different from my current job, I guess just different genes so even being a bit more physical he has started to gain muscle.

My problem is that im really jealous, he has the body type ive always wanted and that I could never achieve even when I used to go to the gym regularly. Im happy with my body but it makes me feel bad that now when we wrestle or goof off hes significantly stronger than me, and while I'm so happy for him and he looks super hot I feel really bad that I know I won't look like that unless I go to the gym a lot, which I don't have time for right now.

Especially him being stronger than me has started to make me feel really insecure, and hes starting to notice but I dont know how to tell him since there's nothing I can do and its not like its his fault he has good genes for that kind of stuff. I dont really know how to work on this or how to ask about it with him in a way thats productive.

TLDR; my boyfriend is getting stronger and more manly than me and I feel bad about it :(
