Hello, I am 18 years old and lately ive had a problem that has been worrying me a lot. My legs seem to have been very tired in the calve, groin and hamstring area. I've also had problems with my erection, It seems to not be as hard as it used to be. I still get kind of hard but I use to be as hard as a rock and now it seems like my penis isnt as hard or that bulging feeling. The erection problem has been happening for about a week in a half now and the leg problem for about a week. I workout reguarly and dont have much stress on my life other than this. I am also not a virgin and have had sexual intercourse and been sexual with some women.
This is worrying me very much as the summer is just starting and it is before my college year. The other day i had an encounter with this girl i was talking to where we were in the middle of some foreplay and she asked to have sex but i declined becuase i wasnt getting hard enough but i did not tell her this. Help would be greatly appreciated.
