Hi, I am 32 years of age. About 4 months ago, I met a girl that I love, and she felt the same, Problem came with sex, My penis gets hard but in limb state too, some days it gets fully hard, but when i try to penetrate her, I find it hard to enter and suddenly the erection goes away. Sometimes I lose erection while inside her, it has been four months now and we are both afraid to have sex. What should I do?
