Amusingly I would say it is not that it is the guys first time that seems out of place to me. My first time was alright. Wasn't the girls first time so that helped.
But neither of those girls appear to be virgins to me. The only virgin I ever deflowered was far less fun than one would expect. She complained it hurt, she bled as many do. Had to be overly gentle and I couldn't finish. She claimed to enjoy it, I kind of doubted it. Still it is an experience. But it is rare that a girl will be... "ready" for the first time. For lack of a better word.
