You are in couple and your sex life leaves nothing to be desired? You are both concerned about the growth of the other, you make sure to surprise you on a daily basis, to maintain your complicity, not to sink into routine and boredom. In other words, you have found the right partner for you: no need to go elsewhere. You self-suffice yourself, so do not ask yourself if you should try new practices such as swinging.
One last tip: you are satisfied with your sex life but not him? He often asks you to try swinging, "just to see"? Do not give in to her request if you are not completely up. Say no, it's your right!
