I don't know if you properly understood but I was after how long would be a reasonable time to go without changing my underwear. Then again I guess you did hence several people telling me what I expected - I should change every day... which I shall continue to do so. I'll just put up with my smaller undies every so often.
And yes, I do plan to get some more pairs soon. I'm hopefully going shopping on Tuesday so I'll most likely get some then.
I would also imagine, by the way, that it would be a good idea to change my undies after I've cummed in them, for one reason or another.
I already do, and have been for quite a while, no matter how much cum there is. If there's just a little bit (by which I mean, a very little bit) though, would cleaning it off be good or is that disgusting as well? I would imagine that would be disgusting regardless, so I doubt I'll give it a try, but it'd be nice to know what you all think.
