As for rashes, statistics say far fewer rashes occur on cloth diapered babies than disposables. Disposables are plastic therefore do not breathe the same as all natural cloth does. The thing with cloth is that if you leave cloth diapers (usually wet ones) on too long then you'll get the rashes. You need to change more due to less absorbency (or wicking away of moisture). If you get yeast rashes in cloth they are very difficult to get rid of, and a lot of ladies have had to use disposables for a few weeks to get control of it. But more rashes happen from disposables, that's a fact. Sorry, I did my research
As for sex, it's awkward, belly however small is in the way, and I truly just don't want much of it. It all depends on the person and how hormones affect them. Some love it, I'm not one of em. Plus my DH sucks at romance and helping around the house, so that usually affects his chances, lol
