I've been with my DP for 4 years and I have to say, it is the goo that is the glue for us. No, it's not the only thing that keeps us together, but it is the one thing that draws us so intimately close. I just love that magic place of mind warping orgasms that we escape to most nights (and sometimes days). It is very rare that either of us is not interested in sex when the other is, though it does happen from time to time. Even when it's the wrong time of the month we're still intimate, just in other ways that don't involve penetration.
A good sex life makes up 10% of a good relationship.
A bad sex life counts for 90% of that relationship.
I've never heard of any relationship breaking down because they were having good sex. People leave when there is no sex, or bad sex. Even if I'm tired I make the time for my partner, because of how it makes me feel. It's better than a spa day of pampering!
We do have children in the house (my children not his). One is not quiet a teen just yet. We sometimes arrange for him to be baby sat every so often so we can go off for a night or two on our own as well as going away on family breaks. My children have become so calm and secure since I've been in this relationship.
I'm not a young buck, but I have never been loved this much and I've never had life this good. I always thought "happy ever after" was all just fairy stories, or that it would wear off with the daily grind, but it doesn't. Not with us so closely intertwined!
I was married twice before to men I didn't want to constantly be having sex with and I had a list full of reasons why it was so. A long day of work. Kid's tired me out. Didn't sleep to well the night before. You name it, it was an excuse to go to sleep without intimacy.
I couldn't imagine being like that with my current DP. Like I said, I love our magic place. It's the way we unwind at the end of the day. It's how I know him and I are on exactly the same page. We're two parts of the same thing. He's my everything.
