Really? It's not a stupid question, but it's sure an abvious one... Unless you're medically required to wear diapers, almost everyone who lives with someone else has to at least sometimes NOT wear diapers in deferrence to somebody else's feelings, over concerns of being "discovered", because of feelings of shame/guilt/embarassment, etc... Living with somebody who is 100% supportive of the AB and/or DL lifestyle is clearly the exception, not the rule.
So, of COURSE if you live alone, and DON'T have to worry about somebody else's feelings, don't have to worry about being discovered, etc... you wear more often. Sure, there are exceptions, and we envy them, but anybody who spends any time on an AB/DL board or forum know that's what they are, exceptions.
There are tons of reasons why a "real" AB/DL might choose NOT to wear diapers. Living alone negates about 95% of them. About the only reasons an AB/DL who lives alone doesn't wear diapers as often as they want to are cost and convenience/hassle/comfort. When you live with somebody, you DON'T wear all of the times you want to for LOTS of reasons. When you live alone, there are VERY few reasons left not to wear any time you want to... The end result? People who live alone indulge themselves more. Shocker.
If it isn't patently obvious, I wore rarely when I lived with wife/family. Now that my kids are grown and I've separated from my wife, I wear much, MUCH more often, normally 24/7. What a surprise. Discussion?
PS... Absolutely nobody wears MORE diapers "because" they are with somebody. All of the answers will be either "My partner/wife/roommate accepts me, so it wouldn't change if I was alone.", or, "Yeah, I wear more now that I live alone...". There's not going to be anybody saying, "My wife just LOVES diapering me so much, she diapers me even when I don't want it... Hell, I diaper MYSELF just to make HER happpy.. I would NEVER wear diapers so often if she didn't make me wear them!". If there is, I'm calling BS on it in advance
