Just because someone else does it different or even better is not a bad thing. Pay attention. If you don't want it different every now and then, they wouldn't do it. Example: I have a thing for Asians. Married twice, both Asians. Last long term GF was in the lifestyle with me. She was a redhead, 5'3", 110 lbs, sexy as hell. we swapped one time with this couple where he was a muscle guy, I am not. The girl was a black girl, 5'0", 120 lbs, and an ass that did not quit. Point is, it was different in the way they look, acted, what they did, and damn what she did to me (zero gag reflex).
Again, if you don't what you are talking about, you need to relax and let the people that do know talk about. I'll take questions but unless you ask a question to me, I am done talking to you. My stupid meter detector is too high.
