Your late father built you an Anti Horny Defense Android, or A.H.D.A.

Seeing as your dad didn't want you to be a pathetic virgin for the rest of your life (You're not. You have plenty of .), he built the AHDA so that you don't end up becoming a wizard by the time you're 40 years old.

Sure, this wouldn't be such an issue if the AHDA didn't seem to want to tranquilize any females in your vicinity. Also, she 'insists' you have with her whenever your adrenaline levels spike. You don't even have to be aroused.

The design is very human.
