Red flags or no?

I decided to try dating again. I’ve been talking with someone (a week now) and he brags about his sexual prowess. He said he makes every woman O. He’s good at eating a girl out. He’s never failed at making a woman come.

At the same time, he told me women cheat on him. He said they cheat on him because he isn’t attractive and because he’s overweight.

I thought intimacy was a huge part of a relationship. Isn’t sex supposed to bring a couple closer together? If he’s so good in bed then why do women cheat on him?
