What injuries have you sustained during sex and/or love play?

That bit of tissue is the frenulum of prepuce of penis.

Or was, anyway. Yes, that name does ring a bell. Following the link to a definitely NSFW page, I see the sentence:

It is possible for the frenulum of the penis to tear during sexual activity. The frenular artery may be severed, causing significant bleeding.

Yep.
Also from the Wiki link, my frenulum linguae has come in for a bit of a bashing on occasion, too.
