I am very very prone to UTI's and cystitis etc so I'd MUCH rather use too much lube and let out a few fanny farts
and other noises than having to go through another UTI!!
I wouldn't worry about it honestly, what do you prefer, a few fanny farts or another week of agaony, feeling run down, trip to docs,
another course of antibiotics..
It's just not worth it, so I say, if it helps, use as much lube and more as you feel you need.!!
