I've been acne prone since I was a teen. Last week I got laid, and beforehand had very minimal acne on my face. I ended up going down on this girl. or after giving someone oral sex as this can sometimes cause your gums to bleed. O Avoid getting semen or vaginal fluid in your eyes. My BF just informed me after the past few times he gave me oral sex it made his mouth numb. Alot of them including the one I use on my face has menthol in it.
