Being more of a bear, I've never really had the chance to feel up, cuddle, or have sex with a muscular man. In my area none of them seem attracted to a bigger guy with a belly.
Experiences? What is it like? Big difference from an average body?
I've been with quite a few muscle guys - Used to be pretty built myself but, i'm 53 now and, while in pretty good shape, not what I once was .. so, to answer your question based on my own personal experience. Muscle guys - like all guys, go for different things depending on the guy .. I think, in general, people go for any sort of ideal whether you think that ideal is huge built, toned, classic bear, twink, daddy - whatever I think the reason why a person works on getting into whatever you believe your ideal shape is to maximise widen the pool of people who are attracted to you so you have choice. When I was in my best shape, I didn't always go for other built guys - sometimes it was a great face, or a great arse or just some instant attraction. My goal was to open myself up to having the choice to be with someone who I felt attracted to on the day.. not to always attract like for like
Personal experience I've had with muscle men .. I'm visually attracted to guys that are in perfect shape but almost every time I've been with one, once you get over the eye candy and get down to business, I personally find a rock hard arse less tactile than one with a bit of natural wobble. Classic example - Was horny AF last night and decided to hook up with a 25 year old who was hotter than hell, built somewhere between a smaller version of Jason Mamoa but bigger than a worked version of Zac effron .. pretty much my ideal eye candy .. but once we got down to it. kinda didn't like that he was so hard all over, just didn't get that bury your head deep in his body feel that a nice juicy fleshy but still in shape arse provides..
Everyone has their own tastes and I think what is being leveraged here is that most people are attracted - at least visually, to people who are in shape in general - doesn't mean that is a hard stop or even a overwhelming preference
