bareback is the best
Bareback is much more enjoyable. The feeling of a warm wet pussy on the sensitive skin of my bare erection is irresistible.
I have sex 99% of the time with my wife and I know she has no more partners. Occasionally I have bareback sex with a sweet young asian girl, and she uses protection with everybody else. Given those parameters, I feel relatively safe.
I don't think I would come right out and ask a massage girl for bareback, but if she gave it, don't know if I could say no.
