There are moaners, typically around the 'I'm a sex ghod and you shouldn't need it with me' issue, but if you don't want to say 'tough shit, it's lube or no fucking', you could say that it's important to use lube when you're having extended hot sex because of condoms...
But this is is why some people pre-lube. The moaners think it's them that's got you wet, not the bottle.
