If you want to downvote me for using Urban Dictionary, that's fine. First base When you get to first base, you have been lucky enough to have been kissed.Some people only consider French kissing as getting to first base.
Leman and Bell, in their book A Chicken's Guide to Talking Turkey With Your Kids About Sex, make use of it to aid parents in the discussion of puberty with their children, dividing the topics into "first base" ("Changes from the neck up"), "second base" ("Changes from the neck to the waist"), "third base" ("Changes from the waist down"), and "home plate" ("The Big 'It'").
Second base is direct physical contact, usually meaning his hands to her breast.
My brother is of the opinion that if you haven't slept with a girl by at least the third date, then the relationship is going nowhere at best, and she is borderline using you at worst.
The older I get though, I move closer to thinking that maybe the best time for sex is when you BOTH feel really ready and desirous of it, no matter how many dates that entails. I'd say I ranged across the spectrum just like you, though welbywife and I waited 3 months before getting naked.
Perhaps the older and more mature you are, the sooner that is, but the important thing is your state of mind, not the quantity of dates engaged in. And what is the range for this kind of thing, anyway? Depends on the situation, really - is it love or lust? The older I get, the more I think that it's ok to feel that I need some time to get to know a potential partner before having sex.
