The only boundaries are the ones regarding sex/dating/seeing other people (exclusivity essentially), which we set together, that's it. For the most part, I let her make decisions based on common sense.

If she wants to have coffee or go to lunch with a male coworker, no problem. If she wants to go dancing (which she does only once a year lol), that's ok.

If she wants to dress nicely and sexy, I literally encourage her to do so so that "other guys can look at her and make her feel like the hot deal and she's then all riled up and ready to go when riding me".

Everything's like this. If she decides to cheat or be with another guy, no problems there, I just won't be there when she's back, but I will never tell her what she can or can't do cause I don't own her nor act like a jealous little bitch.

In addition, I always make it clear that once she's gone, I'll "finally" be free to suck on some bigger, different tits, so to speak.

Can a long term relationship work without setting up explicit boundaries?
