My Boyfriend Doesn't Want To Have Sex With Me Anymore — Now What?

Q: How little sex is too little? My boyfriend and I have been together for a little more than four years (we're both in our early 30s and just moved in together) and we just... don't really have sex anymore. It'll be like a couple times a month. We're both busy and stressed with normal work and life stuff, so I know that's part of it, but the lack of sexual intimacy is really bothering me, even though the rest of the intimacy (cuddling on the couch and in bed at night, hanging out together, talking about all sorts of stuff) is still there, as warm and loving as ever.
