hi, i am in my early twentys i would consider myself to be in good shape with maby 11% bf and, but my erections and orgasms have been 70% at best, of the norm. and has been for 3 weeks now. my diet has not changed, i still work out regularly, i am also not on any gear, or comming off. I am worried that maby a have some broken plumbing or something. i can still make things happen but i feel like an 80 year old man. whats wrong? does any one have any advice?
