Just a rant about my no strings attached situation

I have been hooking up with this guy on and off for about three years now. Its more of a no strings attached kinda deal. We talk to each other just to make plans to meet up and have sex and then when we see each other its just sex and then we go our separate ways. Lately I started feeling a bit self conscious. Here is the thing I’m not bad looking, I think I’m pretty and I have a decent body… Im a mom so I have some stretch marks and some lose skin but still not bad but this guy is like a guy I never expected to even look my way… He is a personal trainer and has this hot muscle body and he is really really good looking. I just keep thinking that there should be way more hotter or prettier girls he could be having sex with instead of me. Dont get me wrong its not like I have feelings for him or anything. Its the last thing I want or need right now and he doesn’t either we are both way too busy for anything serious and Im looking at him like some stress relief. He swears im the only one he has been having sex but in my mind it kinda seems impossible since he looks like that. Maybe he really just dosent care if I look okay or not and its literally just having sex to have sex...Honestly idk why I am making this post. Im just feeling a bit self conscious today…
