Ok, i'm 20 years old, i'm a virgin :ugh ... But... i recently made a beautiful and nice girlfriend. We "dry sex" a lot but when she start giving me a blowjob ( first time 2 ), i loose my erection. Last night, we tried to have sex but the same thing happened... i was hard but when i put the condom on my penis, i lost my erection again... what's wrong with me !?!?! Am i 2 nervous ? Thank you.
