Not necessarily, but they can be embarrasing or less than desirable encounters depending on the circumstances. (Nothing enflames lust like a hangover in the morning.) If you are studly enough to land one damn near anytime you like, then I suppose they could get kind of boring for you. If you are NOT studly enough, then obsessing about getting one can can get tiring as well, at least to those around you..
it really is a personal choice, if that is what the two people want then some would say its ok however if you have to ask it may not be for you and martinezd is correct there could be horrible consequences
