My SO [now ex] cheated on me three weeks ago after almost 7 months together.

I went to a party type city in Mexico a week ago, and met this guy. I’ll call him P.

We’ve been having sex since we met [always with a condom and I’m on birth control] and it’s honestly way better than sex with my ex. He makes me orgasm and his penis is the PERFECT size.

I know it’s bad that I fucked a stranger, and P is a rebound. But I’m not planning on continuing it. I know I need space and not sex right now.

Update: my ex is now dating the girl he cheated with and I ghosted P because of the guilt.
