Hello, brothers. 27 yo male here. Spent a month overseas, have been really busy. Haven't had sex in 40 days total(I don't fap). I have been extremely horny all this time. Got home several days ago, met this cute petite 20 yo, invited her over, first time finished fast. Second time went limp, tried for the third time -- the same. It is like I completed my mission and my dick didn't wanna do the job. Then she left. She wants too meet again, but what the fuck is wrong with me? Have any of you experienced it? Is it OK? I feel awful, guys. What do I do to get to my normal sexual perfomance level?
