Apparently I like them young, myself. I started to post a thread about why, but then decided, who cares? There can be something very, um, hot about being dominated by someone younger, though. I say, go for it, but be careful of your heart.

As for the switching - whatever. If you can talk with him, I'm sure you two can find something comfortable. If you can't talk, enjoy it anyway, but it might be shorter then.
