Ok- now that I dont have a glass of wine in my system...
I dont think there is a set outline for sex.
I have been in relationships of all extremes.
Some I dont, to this day, remember their names.. but we were enjoying ourselves rather quickly after sharing introductions.
And, I also dated someone for almost a year with absolutely no sex.
In fact, that was one of my favorite relationships.
It was back in the early 90s when trucks with huge wheels were popular.. and he had one. So I would follow him around Rio Rancho ( a little bitty town) when I saw him and he finally pulled over one day, and we sat on the side of Golf Course road and talked for almost 3 hours.
Cute little bugger he was. (sigh) Great kisser too.. but no sex.
I believe it is about the chemistry of the relationship that should dictate when sex happens and not some oddball social rule.
In fact...............My husband was meant to be a one night stand...
