I'm 29 years old and I do not have precum. I've masturbated and dry as a bone until I come. I have looked up lots of information and can't find anything about guys not having any. I've discussed with my friend and he says he has a lots of precum. Even most of the men do. I feel like I'm missing out on something special and I've also read about how important it is in helping to deacidify the vagina and help in fertilization. Is it normal? Or should I consult with a doctor? Any comments would be appreciated.
