how long to wait for sex

Hayley • I'm 18, huge nerd with a huge heart and unrestrained humor.
I'm only 17, been with one guy but I'm dating someone else now. He's a sweetheart, no pressure for anything at all and I don't plan on having sex again with anyone for awhile.
I'm just curious though, when do you guys think it's been long enough for sex? a couple of dates? A couple of weeks? A month? More? As long as both parties are up for it of course
