It’s the age old question, does sex really change everything? In the past when sex was considered something more sacred,yes it would.
Sex used to be something you did with a person you had strong feelings for. So it was natural to think by having sex, you guys were more than friends. If either party thought it meant more, Then you had to have a awkward talk about how you just wanted to be friends and someone’s feelings got hurt.
Now days sex is as common as a cold. It’s lost all meaning. So if you wish to have sex with a friend on a drunk night you laugh about it the next morning and go to waffle house later. In short it doesn’t mean as much anymore.
As long as they(or you) dont have legitimate feelings for you, you’re good. If you’re sure then just don’t, better safe than sorry.
