Honestly doesn't matter. Every guy is gonna have a different desired length of time. Focus on something more Important instead. A man will leave a good fuck no matter how quick or slow she gives it up but if you can get down to the core of who he is and convince him you're pretty dope he'll stick around regardless of the sex. Just go and meet people get to know them and have fun thinking about timing for sex and stuff like that is just your nervous brain distracting you from the vulnerability required to actually find a good fit.

There's no specific "wait time" just wait until you're ready and want to. I personally only ever wait at the most two weeks. That's partly because I don't think sex is a thing I should have to wait for or the guys I'm dating should - it's not a huge deal to me because I don't associate it with love. I know other girls who are waiting for marriage and that's great too, you just have to know you're ready. I mean the average amount of time people seem to wait (among my friends and people I know) seems to be 3-6 weeks after being "officially" together, but if it's not for you wait longer or less time. Hope I helped. (:
