When did you have your first kiss or go on a first date?

I've seen alot of people already have had they're first kiss and date but I was wandering If 12 is a good age to start. I probably won't until I get to go on a date which will be by the 10th grade or sooner. I've already had girlfriends and my sister is going in the 9th grade and she might be allowed to go on dates and kiss but yet I dunno. She can have her boyfriend over but they can't go upstairs. (My parents don't trust even though i'm a scout).
