Good morning, I m kind of worried, I used meth for the first time n it was good and all but my girlfriend does it more often. She suggested she do a bump which means she inhales meth and then gives me oral sex, while she gives me oral sex she exhales it. I m worried bc I ve noticed that my private part seems irritated or burned, can meth vapor or smoke burn your skin or in my case my private part, thank you.
