See a Dr. We can't advise you what spots maybe. Only a Dr with an exam is going to be able to tell you.
I really need some more advice, ive found out that the spot is called the "Sulcus", but im sorta dismissing it on the account of these reasons. Me and my girlfriend had sec 13 times in 2 days.. and have continued to have sex multipul times on the weekends. they get red when irritated, but when they arent it goes to a purplish color, and starts too fade.
I mean, they arent like bumps, there just spots.
And they get really red only when we have sex or she gives me oral. They are only on that part of the head too, and I think its cause that's the part that hangs out farthest, and is more exposed to my boxers / her teeth.
Probably nothing, but only a Dr can tell you for sure what is going on.
