After 37 1/2 years, I guess I'm giving you the long range perspective.
Here goes:
What happens to your sex life as time goes on??
We've gone through several cycles. It isn't as frequent as it was in the first year or two, but then are times when it seems like it's back to that level. Some of the things that impacted it included kids, hormonal changes and life in general.
How does time effect the consistancy of sex?
Actually, it's better than in the beginning because we've learned how to please each other and we take more time. It's less about the act and more about the enjoyment. Also, we are still willing to experiment, so it's still fresh.
Do you feel more/less attracted to your partner then you initially did?
I really don't know how to answer this and be clear. When we were first together a lot of the attraction was physical. Now, it is more sensual. I still love how she looks, but what attracts me is how she reacts to my attention.
The best way I can sum it up is that it has all changed as we have changed. Our relationship is just as intense, but for different reasons than when we were first starting out.
