I think that I can relate to that as well especially the Gymaholic's input.
I'm not skinny myself but not really muscular yet and I feel like it hinders my response rate from big, muscular guys who are into muscles.
Personally, my only sexual contacts could be those related to muscle worshipping, testing mutual strength etc. and jacking off to that. And actually quite many guys that I contacted would be down to that but the dialog develops as follows: -
- ok, but what are you into?
- All the muscle worship stuff I just described
- Yeah, but in sex
And then I figure out that muscle play is not sex to him
