So I just masturbated quite a bit over the past week, and I'm now noticing a red and swollen perineum with what look like little scratches, and occasionally bleed. I have no pain or burning at all and am only bothered by it if I run my finger across it. I have noticed this happening more often but only after I masturbate or have sex. I'm wondering if this could just be irritation from masturbating or something else.
