Weed can do that. Don't write it off entirely. Try a different strain. Don't rush into sex. Relax. Listen to music. With good pot you'll feel the music caress you. Once you've achieved a state of comfort and euphoria, then have sex. Marijuana can greatly intensify pleasure. It can also cause you to freak out and have a horrible time, as you can see. Oddly enough, I find that when I tiptoe into pot I'm more likely to develop negative thoughts than if I jump headfirst and get myself super high.
God, so atrocious in the Old Testament, so attractive in the New--the Jekyl and Hyde of sacred romance.
-Mark Twain
If people are good only because they fear punishment and hope for reward, then we are a sorry lot indeed.
-Albert Einstein
