How long should you wait to have sex?

Beth
I've been talking to a guy for about 2/3 weeks and we've been in a relationship for about 5 days or so, and I've already had sex with him, one friend thought it was completely wrong and another thought it was completely fine because at the end of the day it's my body
What do you guys think? (You won't offend me because I'm 100% for the "it's my body ill do what I want with it" mindset 😂"
