Says he "felt soiled". Apparently the concept of sexual recharge was not executed well. Seen commonly in anime, in my humble opinion, one of the better versions was offered in the original Sekirei. Remember when Sato tells Tsukiumi (a powerful, but as-yet-unattached sekirei): "you might want to turn your eyes away, the shock may be too great"? Immediately, someone on the scene covers up eyes of Kuu, a child-like sekirei. In turn, Kuu peeks between fingers, but just late enough to miss the most explicit parts. The air of humor and suitable wholesomeness made it work.

I actually found BokuH rather entertaining and mostly because I get to hear Shimono Hiro scream out perverted things again instead of voice some angry shota in otome games.
