Help me! what will i do?!?

I have a problem. me and my boyfriend have been having for over a month and i cant seem to , like he can go forever and its almost like im numb down there, i dont feel anything in fact, I dont know what is wrong with me, i feel as though im an alien with oddity powers. Ive found that i can control his , but i dont feel anything so it doesnt really make a difference. Help me! oh and i like drinking blood from his finger tips.
