I have an issue regarding sex. First couple times I've tried to have sex with my girl I couldn't get hard, probably due to nerves. A while after she gave me head and I was able to get an erection. Not tried having sex since. I want to be able to last a decent amount of time if I can get hard. Is it safe to assume I'll be able to get hard with her now since I have once? I've been considering condoms with some numbing agent to help me last longer, but don't want this to kill my boner if i manage to get one. Without it I think I'll bust too fast. Is just a condom enough to reduce sensitivity without killing my erection? Would drinking a few beers before also make me last longer and reduce nerves? Thanks
