Heavy weight lovers??

I recently started talkin to this guy and things are going well...hes the second heavy set dude I've ever dealt with and I wasn't intimidate with the first because I was thinkin too much I guess...Do any of you ladies have a heavy weight spouse if so is the sex the same as someone whos not...like do you always have to be on top or is it doggy style only?? I'm being so serious so plz don't take offense I'm thick so I really wanna understand how this works...I even tried to find some porn to give me an idea and no luck...plz share some of your experiences with me good or bad
