<human>: Can you summarize the given text in a few sentences?

So my girlfriend and I have been going out for 8 months. About a month ago we hit a rocky time because she made some mistakes and in a minor way cheated on me. After that I gave her another chance but I said she has to come clean about stuff and tell me things. Well we have been doing great, but more recently I found out she has been sending sexual pictures to 2 or 3 guy friends of hers. She is naked but she covers up, so it is almost like she's teasing them. I have on multiple occasions given prime opportunities for her to come out and say it, and I even asked directly about one guy who I know she has sent pictures to, and she says she would tell me if anything came up. She says she loves me and is heartbroken and totally distraught at any thought of losing me, yet she is doing this behind my back. Ultimately, 2 questions. Should I confront her about it? And also, how do I even bring this up to her? Thanks.
<bot>: girlfriend has been sending sexual pics to 2 of her guy friends. Nothing bad, covering up, but it still annoys me. What do I do?
