In a LTR with a girl who is sexually out of this world, great body, will literally do anything I want. Begs me to call her a bitch/slut/whore and spank her. Let’s me facefuck her, tit fuck her. Everything I could ever want, and great body. The thing is, I still get bored with the sex anyway and want to sleep with other women because I like the thrills. Anyone experienced anything like this before? Have suggestions on how to keep the sex interesting in a LTR?

Edit: i’m not going to cheat
