I am 18, and my girlfriend si the only person I've had sexual activity with. We have done no penetration yet. But sometimes when i flaccid and we start kissing, I prematurely ejaculate (sperm, not just seminal fluid) a very small amount while flaccid. This has no effect on my erection later on and has no effect on the amount of sperm I ejaculate, but it is quite embarrassing, although for now she simply believes it to be seminal pre cum. I do not feel anxious when with her and in fact feel very confident, but I do not know how ot fix this problem. i masturbating atleast once a day every day before I met her, and read that some of my pelvic muscles could be weaker, and Kegel exercises could help. What should i do?
