Love with a lonesome 47 yo woman

My problem is that I'm a bit impulsive. I just do what I want, without thinking about the consequences. Just like now. I feel like having a date, and I need to get it right away. My boyfriend is unavailable right now, so I need someone else. Will you sacrifice yourself?

At home, sex is so terribly boring; the only position I get is the famous missionary. I'm fed up with it; I want to experiment with other positions.

I'm a jack of all trades. If you don't want to leave your girlfriend home alone when you come to visit me, feel free to bring her along. The more souls in bed, the merrier!

If I'm being completely honest, my boyfriend doesn't want to have sex with me anymore because I'm chubby. I'm always horny and can satisfy him. I even caught him cheating. Why do I still have to be the good housewife and not be allowed to have sex with another man?
