I had sex with a new partner I've been dating for the first time on Friday night. It's now Sunday and I've just found what looks to me like herpes blisters on my penis. I'm devastated because I've got no idea if I've gotten it off her or potentially now given to her! My head is a mess. I really like this girl and now I have this to deal with. I don't know how to speak to her about it or bring it up. She's so lovely and I don't want to upset her.
