What are the chances of getting an STD?

Having unprotected sex can be risky; probably in the neighborhood of 50%.
Nearly nil if not promiscuous & partner isn't & use safeguards.
1 in 6 chances are pretty high so stop sleeping around. If you don't sleep around with people who sleep around then you have nothing to worry about ! If you want to marry someone and they had a past you should probably get them checked so your life ain't miserable ! Remember chances are high! Don't " sleep around "
That depends on who you sleep with, how many ppl you sleep with, and whether you where protection.
U can get std from anal sex vaginal sex oral sex. The risk of getting stds can be significantly reduced if u use a condom.
