I received oral sex for the first time last night from a girl who says shes only given it to one other guy I did this without a condom and I had a small blemish on the middle of my penis from masturbating previously it's light pink it was about 2 weeks ago when I masterbated and got the sore it scabed over and eventually the scab fell off not it's a light pink color (like it's not a open wound anymore ) cause it's just a blemish (discoloration) an I received oral sex without a condom while having this blemish what are the risks for any disease
