Well put... I personally have seen my sexual tastes do a complete 360 degree turn at age 52- and tried stuff I never thought I could get into, (and loved it). And thus, I have to agree with Cyrus- Should I meet someone who says "I am exclusively this, or that," it sends out a signal to me, that this would not be someone I would want to have sex with beyond a casual hook-up. Always doing the same thing in the same roles, (maybe doing it over a different piece of furniture,)- I think it would get boring quick.
