If you are a man and are interested in women especially those with kids, then make sure you understand the most important commodity is time.
Also, you must realize too that her children are part of her, so you will need to manage your expectations and also understand that for her to fully trust you you have to be in with the kids as she doesn't want nor desire to deal with the mental damage from a guy that is into baby momma's but not the kids.
There are pro's and con's to this, if you both are consenting adults and it is all about transactional sex, then this can be a win-win, but understand the boundaries.
I realize this article is four years old, but there is value to women that love and raise children. They have empathy, compassion, and the ability to care for others. It doesn't mean there aren't women that are childless and single that don't, but they do have to deal with realities every day.
So quite a few women that desire a bit more (think sexual engagement on a regular basis), will be concerned about the size of the authentic masculinity not the size of his wallet or body. But do keep an eye out, if you see a use or abuse type of situation understand that there is an imbalance that you have to watch for too.
