Herculeisure 

Another way to describe having sex with a woman with huge, bodybuilder style muscles, the "leisure" part refers to the fact the woman will allow you to sex her when she feels like it, knowing full well that her male partner is afraid of getting his ass ripped in half like a phone book if he forces himself upon her

Henry: So Bill, did you and Mary enjoy your round of herculeisure last night?
Bill: Yeah, it was awesome! There's nothing like the feeling of huge femuscles against your naked body
