That is precisely why I mentioned the social aspect. You are a social person and you need social outlets. Part of the fun of sex is the social/relational part. Well, you'll have to get that need met elsewhere. Just don't make the mistake of seeing "nurture myself" as only activities you do alone.
Are there activities that you do with your kids that are also nurturing to you? What if you scheduled some special Daddy/kid alone time and took the kids to do something. Wouldn't it be nurturing to yourself to have them tell you what a terrific time they had?
To be sure there are also some very nurturing "alone" things: solo sex, a good book, working out, hobbies (art, model airplanes, origami, playing music). When was the last time you went alone, got a cup of coffee and browsed in a bookstore for a couple of hours by yourself?
