My husband did something REALLY weird… should I let it go?

FYI: we got married 2 weeks ago.

He was on the phone having phone sex with somebody. I caught him, so I don't care what he says. He denies it. He already ejaculated on the floor, so I asked him "Oh yeah? What's that?!". He tried to tell me some bullshit lie with a straight face, that it's skin cream. But what really bothers me, is when I called the phone company to see who he was on the line with. They said the call came from his mother's house. WTF is going on?
