Hi, When I Masturbate Lately Which I Have Always Liked

Hi,
When I masturbate lately which I have always liked to. It seems like I am grasing the top of my foreskin and when it heals it scabs over.
I am a bit worried as the has only happend lately and I do use protected sex.
A girl said to me it might be herpes when giving me oral sex which I hope it's not.
If I leave my penis alone for a few days it heals.
There is no puss coming from the scabs it's just a bit sensitive before the scabs come.
Any idea if this might be herpes?
Thanks
