6 weeks ago my gf performed unprotected oral on me and we had unprotected sex, the next day a cold sore appeared on my lip, I think it was from kissing her a lot and from her make up but it Defo wasn’t present at the time we had sex, a week later I masturabted and had red patches over my penis and then followed a tingle, after a few washes the went away, then now Ive got a painful lower back and swollen lymph nodes, she had a swollen lymph node a week after we had sex, they’re the only symptoms I’ve had along with feeling sick because I’m worrying so much, I should also add that I’ve had no outbreak of anything, and I’ve had no problem with urination. can anyone help me out on this because I won’t be able to live with myself if I’ve given her this disease, thanks.
