So... when I first started seeing my girlfriend, I could fuck her for an hour and a half. Now I'm cumming in like 45 seconds. This has been an on-and-off issue in my life. Sometimes I fuck like a champ, sometimes I cum really quick. Lately I've been premature ejaculating like every time for the last few months. Even when I masturbate (which is rarely) I'll cum as soon as I get aroused.

This is embarassing for me and my partner is a sweetheart about it, she pretends it doesn't bother her, but let's be real. I know it does.
