After a month of courting, three weeks of official dating, a talk with Hotch and an introduction to his mother, Derek knew he couldn't wait much longer. At some point, he was going to have to put out before his sweet Penelope started having doubts about his desire for her.
Lack of desire, he suspected, would never be a problem in their relationship. The problem was that he wanted her too much, in that "I want to grow old and die with you" kind of way, and he wasn't sure how to handle that. It was big and scary, and despite his extensive in the bedroom, he was afraid all those messy emotions were going to interfere and he'd find a way to screw everything up. Now that he'd found the woman he wanted to spend his life with, it was vital that he get it all right. The last thing he wanted was for his panic and terror to keep his bow-chicka from bringing the mow-mow, leaving her disappointed and unwilling to come back for more.
His father once told him, "Derek, to be a man, you have to learn to face your fears." Of course, he was a gangly eight year old petrified of Antoine Jones pantsing him in the lunch line (again), but it was still solid advice that he'd relied on over the years. Deciding not to delay any longer lest he lose her anyway, he made plans to man up and face his most current fear on Friday.
