I remember in the early years of masterbation I came, I remember being able to cum. Now, for last three years I haven’t been able to cum. I can orgasm just the same, but no cum. It’s a bit disappointing in bed when my partner wants to see me cum but I can’t. Is there any medication I can take that could help me regain the ability to cum again? Or can anyone give me some insight on why I’m unable to now? Perhaps it’s a condition?
