Well -- for us, it ended up being yohimbe supplements for hubby ;). That aside...I totally agree with dating. People usually either stop dating once they're in a committed relationship, or they never even start. I'm one of the ones who never really dated. Now that we've been together a while and have two kids together, in addition to my son from my first marriage, we're starting to focus on how we can do things that are JUST for our relationship. Everything else in life seems to revolve around the kids, but we're seeing the importance of making our relationship a priority since my husband and I will still be together after the kids are grown and gone.
So, thus far, we've set a "date rule" that we HAVE to get out on a date twice a month. We take turns planning, and make it a game to find something fun and original. We live in a small town, but that's just an extra challenge to our creativity and offbeat senses of humor. There's also little to no money to put into it, so that also adds to the fun of the challenge. Whoever is planning doesn't reveal the plan to the other. It does help add some fun and excitement into a relationship where we know each other inside and out, know what to expect in bed (working on those surprises next), know each others likes and dislikes, life history, political views, irrational passions, etc.
Ultimately, I think the thing that works is different for everyone. The sense of adventure seems to be the major difference between new relationships and old ones. We love the comfort of being with someone long-term, but the adventurous spark dies. So -- something new, something special, something unexpected around the house. Wear hot pink polka-dotted underwear just to make her laugh when they turn up without warning. Whatever it takes. Few people don't like laughter, snuggles and surprises. Contrary to popular belief, every relationship takes some devoted work to keep it alive and strong.
