Question: I started having sex with a new partner two weeks ago. We got to know each other well before we slept together and She told me she was disease free and on birth control so we did not use a Condem. We have had sex twice and both times were very rough. The first time we both had rug burns on our knees. The second time was at least two and a half hours and we stopped because she was no longer wet and I could feel the friction on my penis. The next morning my penis felt like it had a friction burn, very similar to the rug burns I experienced on my knees the previous week. It was also swollen that first day. The swelling went down but there is a small mark where it hurt the most. There are no fluids coming out or anything typical of herpes sores that I have seen or researched. Could this be due to the rigorous sex or should I be concerned? I do have sensitive skin and have had a similar reaction to master bating. I have been tested for herpes before this new partner and was negative.

I have attached a picture in hopes it can help you determine. According to her she had no stds, and again i was tested before her and was also clean. It does look similar to something that has happened before i just want to be careful. Thank you so much for your help. There has been no pain when i urinate, and the lesion had never been oozing with anything. This is three days after.
Thabk you again .
