If it is, I'm in big trouble..... :wink:
In all seriousness, orgasm has many benefits actually. Lowers blood pressure, relieves stress, lessens PMS symptoms...there are a long list. I wouldn't worry about it. If you want sex 14 times a day, I say go for it. Those who are sexually active are healthier. Provided, as LadyJ pointed out, you protect yourself in all the right ways!
The only way I can see it being damaging is if you have a bad heart or something like that and your doctor has told you you shouldn't be having vigerous sex. But again, like LadyJ said, without more info, this is all I can offer.
