Can't get off unless i'm high
So about a year ago, I got the bright idea to smoke weed and masturbate while I was high. It felt awesome, I had never had such an intense orgasm in my life. I started getting high everytime I masturbated. But I recently quit smoking weed, and now when I masturbate I climax far too soon, and I feel next to nothing, it's even worse when I have sex. I'm kinda worried that it will never be the same. So, 1) is this normal? And 2) how do I change this?
