Only had one girlfriend that liked to watch porn, but she only liked to watch gay porn which is not my thing, so we never watched together. She could suck a dick though, maybe that's where she learned it.
I enjoy porn more when Im alone and need the extras stimuli, cause when I got a Cock to play with Im making my own porn right then and there...................IJS YUM!
I used to watch porn when I with an ex fiance of mine. I don't have a significant other anymore but I found getting turned on first with a little porn sometimes got both of us a little more intense.
