Men, if you are at a crazy ass dope party, the odds are teh chick u fuck at the party has done the dirty with someone that day--maybe even earlier at the party. If she is easy for you, of course think that she is prolly easy for every dude. From a health standpoint it is actually more troublesome if his cum is in her pssy before you fck her cause that means you could catch an std if your bud has one.
