I could really use some advice here... my boyfriend has less experience than me in the bedroom (which is saying something) and is so concerned that he will be unable to get an erection, that in the moment, he finds himself unable to get an erection. He has had anxiety issues since childhood and is rather underconfident in himself... and he isn't asexual. he does get into it when we fool around, but once we get much further than second base he clams up. What can I do to turn him on and help? Any suggestions?
