Do men ever feel self conscious about taking their shirt off in front of their girlfriends?

I want to run a little poll. I personally do not have abs and I don't necessarily sit on my ass all day. I work out and have an athletic build for my height but I feel self conscious to want to take my shirt off around my girlfriend because she has a very athletic build as well and I fear that she may have expectations of me having more muscle tone.<br><br>I see on a lot of cheating facebook groups and partner cheating groups that many men are cheating with other men and men have been having sex with each other in the gym. So, you would think that most men are athletic in build but I found out that most men were overweight. Even some athletic men are overweight in terms of body fat %.<br><br>So I want to hear from the men here. Do men feel self conscious about taking their shirt off around their girlfriends and why?
