I gotta say it’s really interesting how since two women who want penetrative sex would use fingers, dildos, and strap-ons, they always have a reliable hard object to use. By contrast, I think gay men assume one of them will have a penis hard enough. That makes me wonder how much fun I could have with a guy if I used a strap on and basically never let him up, and just kept pounding him until he turns into a puddle. I don’t think bottoms are used to that.

Sounds like you have really excellent communication in the bedroom with your gf. To get just the right level of roughness seems like it must be a delicate balance!
