I do mine and this is what makes my sex with her so intense as i can "fuck" her without any inhibitions. In my opinion it is one of the main appeal of the "lifestyle" and it is because of this that your sex life with your wife also improves a lot.
However I should also add that this is only limited to the bedroom, outside in the real world she she is my princess and the mother of my two beautiful children. However in the bedroom she is my very little slut.
Sorry if i came across a bit rude. i just typed what I felt like. Sorry if someone is offended by it especially the ladies.
