I am 24 years male and recently became lawyer in 2017. I have bad habit of masturbation since 7-8 years in fact I masturbate 4-5 times in week. I had sex more than 50 times with my girlfriend. Now I am engaged nd my marriage is in December. Now I am not in confidence that I can do sex better in comparison with my past. When I meet my fiancee I feel hard in my penis for 4 months but now whenever I go near my fiancee my mind starts getting negative thoughts like I just can't do that. Please help me to get rid over this negativity. I'm normal but somehow my mind is full of negativity that I can not do sex and finally can't create a mood for sex.
