Pegging

I recently came across men being fucked with a strapon by women. I never gave this any thought until I saw it. It seems like both man and woman are enjoying this. So I gotta ask. Is this what you guys like? Ladies, have you or do you fuck your man with a strapon? Is it gay for a man to do this? Does this mean that he has gay tendencies if he enjoys this? I just really want to know. I watched a few of these videos and found them kinda exciting. Something new and different (for me).
