And Longhorn88 nailed it. Familiarity breeds boredom. A man wasn't meant to be with 1 woman sexually. That's something as a society we have created in order to survive.
"NEVER" Can't get enough. My gf always gets mad at me. She's the one that always says no. Bur yet when we are out somewhere, she hangs on my arm and get pissed if a chick looks at me. lol
LOL....or the moment you say no or ignore them for awhile they are all over you again what is up with that...I think you men lose contol of your emotions during sex and can't handle it some times....oh let the flaming for this one begin lol
