Just out of curiosity is it normal for your sex life to be kind of sad in your early 20’s…

My boyfriend and I have been together for two years, truly the most amazing man and the love of my life. That being said, our sex life has taken a non existent path… as in it used to be days to a week or two but now has turned into a month or longer without being touched or looked at. Like right now, it has been a little over a month since we have had any form of intimacy. Sex. Make out, butt/ boob grab, anything intimate and it’s starting to get to me….I am a rather sexual person and my man has always been up front about how he isn’t the most sexual, which I am fine with. Also a year before he met me he had a motorcycle wreck which bruised his balls a bit in the process, so now most of the time when we do have sex he says his balls hurt and never wants to do round two or we wait another couple of days, so that’s another factor. With me being highly sexual and one of my love languages touch, it was hard in the beginning, I dealt with a lot of insecurities. But with how much love I hold for this man, I got over them. That being said I have gained quite a bit of weight and my insecurities are starting to come back. Especially since it’s turned into a week at a time for sex into months without it. And when I do try to make a move or be sexy I always get turned down, it has to be on his time which is rare or never it feels like….. Then I try to talk with friends and they all talk about how giving their men are in the bedroom…and then there’s me, like I wish my man couldn’t keep his hands off me and want me just as bad as I want him yk..? Anyway I want to know should I be worried? Is this normal? And yes in the past we’ve had talks about it so idk what to do or how to bring it up again. Any thoughts or suggestions???
