It's definitely had changes over the almost 7 years we've been together because we've had changes. There are stressful times and different things that cause our sex drives to vary. At one point, it was horrible because I was severely ill for a few years (very long time to be ill. I thought I was dying. Really!) and it was hard because even sex was tough when I was that sick, but we'd still do it. It always ended with me being worse sick though.
For the most part though, it's stayed pretty high for the both of us besides when we're going through something really crazy and don't have time or energy. We did have sex multiple times a day when we first got together, but we were teens then & I didn't work or go to school at that time, we didn't have children on our hands, so we had plenty of time for it. That has definitely changed. It's rare if we do it more than once a day, but I usually can't handle it anymore because I get terribly sore, swollen and have quite a bit of pain from just a really rough session
Bummer, but worth it! I would definitely still consider our sex drive to be high though. We hardly ever do it less than twice a week and are always playing with each other, so I am happy that we've kept a steady sex drive & I hope like hell it doesn't change. I know it won't for me, but he did just have a birthday on the 15th & everybody says men lose a lot of their sex drive after 25 & this scares the daylights outta me!
