first of all are you nervous? its all in your head sometimes you can create a problem thats not even real. Im not much of an expert but i have been researching this for a month because i have randomly started  having these problems. The best advice is stay calm,try to turn yourself on,dont get nervous and just dont overthink because if ur mind has to many thoughts are going thorugh your mind your not going to enjoy it and lose your erection. Also try to stay healthy and pay attention to any medication your taking, the side effects can effect your sexual performance.

also here are some natural supplements and food that can increase your libido
1.Ginseing
2.Ginko
3.garlic
4.strawberrys @ banannas=]
