Can dis happen to a man, permature sex is rampant in society today. But i do observe dat anytime i want to have sex my heart will beat during penetration and i will lose d hard erection, but wen i relax again i will stay hard but during penetration i will lost d erection again. Am a virgin i have been trying dis for 7month now but still cant penetrate. Its so frustrating i just run all sort of medical test but nothing wrong. Please nairaland helpers, have anybody experience dis in dia life befor, could dis be fear of having sex and can it cause such thung?
