I was pretty old by the standards of the time. I was raised as such a prude that when my college gf showed me her breasts on our second date, I figured that I had to marry her now or else go to hell. (Yep, I really thought that.)
We got married after college. We were virgins. We didn't have sex until 6 months after getting married. I don't remember the first time other than we used condoms and they hurt like crazy. I think we only had sex maybe three times before we got divorced?
Sad, I know.
Then I met my now-wife a few years later. I was scared to have sex, but we did it right away. Best first-sex. Complete compatibility. She came hard after just two thrusts. Then we had a nice, long second round with simultaneous explosive orgasms that everyone in the entire house could hear (multi-unit house).
And it's been sex every day for nearly 20 years. We have only missed maybe two days, total. Multiple times every weekend day. And it's always very high quality sex; not simply quantity.
