What can cause delayed ejaculation existing good and prolonged erection.Once I had intercourse with a female friend penetrating her three times with pleasure for both sides but no ejaculation for an hour an a half..sometimes oral sex let me finish...but in the case I am talking about we have to stop because she felt tired...and could get her vulva swollen...What is frustating is sometimes when I want to masturbate and can't ejaculate...it only happens if I continue trying for three days or so. For experienced young girls they love that I am riding them that long because of the thickness of my penis. & finish me orally or manually.. Has anybody had the same problem of lack of ejaculation ..( guys or girls..)..and how did they solved it...Can you control it naturally or with vegan products...? Thanks in advance..Lou69
