Fear of the unknown I suppose. I'm more or less in ssmguy's boat, W doesn't like orgasms - she gets panicky before it really happens. I'd have to give up a lot for something that I'm not sure is out there for me as I am the sole breadwinner and have 6 kids ranging from 5 to 20 yrs and together we do pretty well at stretching our money to include some niceties. We've told the kids all along that we'll do our best to prepare them for college, but as far as funding college they need to figure out that for themselves. Should I decide to leave, I would most likely need to pay for college expenses plus all the current living expenses times two households. Every choice has a cost, and in my case the costs are very steep either way.
