Dan Savage at University of Montana - The Question: When I have sex my mind tends to wander and I get distracted and I lose my erection. Please help?
Dirty talk is the best!! ....always catches me by surprise, especially when it comes out of someone beautiful and classy....and never ceases to excite me!! But don't go overboard....the I might get distracted....
