I visited a massage parlor sometime around mid/late October. The masseuse to my surprise lick/kissed my anus twice, very, very briefly. Beyond that, there was no sexual contact other than her masturbating me. About 2 weeks later I had intercourse and oral with my girlfriend. I experienced minor pain in my penis the day prior to the intercourse and it lasted a few days. I assume it was irritation from the handjob. I also discovered what appeared to be a small hemerrhoid (Dark in appearance. Did not appear to be an ulcer/chancre or anything. I've had these before.) Fast forward to about a week and a half and my girlfriend has developed bump on the border of her upper lip. Didn't appear to be a sore or anything, but it lingered for a week. 2 weeks later, she's coming down with a bad fever. She's recovered but now developing rashes on her legs.
My question, does this sound like Syphillis or any other STDs? Could I have passed something through my penis, even though my anus was the only thing that was exposed to the masseuse's mouth? Keep in mind, my girlfriend has had no exposure to that part of my body.
Any input is appreciated.
