HAVING A SLIGHT SEXUAL MALFUNCTION?

Im in my 30s too young for this.. Lately it seems if I don't practice having sex im tighter than I believe I should be like being a virgin all over again. I am dry and when I stay moist its only for a moment then the thrill is gone. I tried ky jelly like a burning sensation and left me itchy and irritated. I been involved with a guy safe sex but I just couldn't stay motivated enough maybe I couldn't stop thinking about my last ex..what else could I do to stay moist and in the mood I used to be a faucet now its like a dry well. dry sex hurts damn 30s should be in my prime
