Querying - agonizing over genre

I know I'm not supposed to agonize too much over genre, but this seems like a distinction that might make a big difference in what an agent might be expecting. Here's the deal - I'd appreciate your insights.

I'm working on my query for my first novel, tentatively titled Spring Rain, Autumn Rain. I didn't write it with any particular publisher in mind, or even with the thought of getting it published at all, but now I'm planning on shopping it around just to see if I can make anything happen. I'm wavering between calling it either a traditional romance or women's fiction. It's very romantic (I think), definitely has the Happily Ever After, but it's not a typical romance. It's more of a love story that has its roots when the MCs are children together, and the main story takes place when they're in their 40s. There's some physical contact but nothing heavy, no sex, nothing I would feel uncomfortable letting a teen-ager read.

So what do I call it? I am querying agents who represent both romance and women's fiction, so maybe I should just choose a term, not worry about it and let them decide?

Thank you so much for your explanation; that really helps. It seems "traditional romance" is probably the way to go.

I appreciate your time!
