This guy is willing to brave tasting hot pennies for 10 minutes for the sake of your orgasm. If he likes to switch things up mid-coitus, it's because he really, really enjoys it. One orgasm is enough, and yet he's still down there. There's nothing gross about periods, but there is something gross about coming up and looking like Edward after the birth scene in Twilight. Practice makes perfect, and his oral skills are pretty close to perfect. He doesn't give up if it's taking a while. Which means he's gotten lots of practice in.
