if you only have one partner you should do it all day and all nite, but if your gonna sleep with more than one person this could mess with your head later in life. like say you fall in love with a gilr i mean you really love her, you might not be able to stop thinking of the hundred of guys she slept with, and even if she says i have only been with two other guysyour gonna say in the back of your head if i slept with 100 glris she must of slept with at least 50 guys and your not gonna be able to stop thinking,maybe she is a little bit of a (you know) so your always gonna wonder if she's cheating on you. also women are addicting, the more you get the more you want. so if you sleep around too much, you may never be able to have a long life relationship. sure you might be able to make it last for 5 or maybe even 10 years, but just like all addicts, you gonna fall off the wagon.
