Anyone experience this in Fsc Cigarette?

Okay I don't know if it is the Fsc chemical because I started smoking around the time it was added. But what I have noticed is that when I smoke around a pack...and I masturbate or ual activity I almost always expierience my bleeding a little and irritation. I have never experienced this in my life and when I quite smoking for months at a time I don't have this problem and when I start back up again it imediatley comes back. So could this be Fsc? Or just cigarettes. Whatever the case it is beyond belief in how horrible this is. And I can't imagine who would do this so the only I option I have is to quit.
