My wife bought me these for the car ride home after the catheter came out:

That girl does have a sense of humour... but they work & they're cheap.
I have one on our bed right now. But for some reason, I don't leak lying down at all.

Leaking out of the pads? Absolutely.
In fact, I take 3 changes of underpants/trousers to work.
And twice I've had to go home within 2 hours, cause I've leaked through.
A bit of an anatomy lesson: girls (presumably) pee straight ahead.
Guys don't - depending which way it's "pointing".
If it's pointing to the side, it can & will pee to the side of the underpants & pee onto the trousers.
Welcome to my world.
To combat that, I wear 2 pads first thing in the morning - a smaller pad put inside a pad large enough for Andre the Giant.
Overkill, but it works.
That's just for the first hour of the working day. For the rest of the day, it's just one 4-drop pad, changed every couple of hours.

Size-wise, I did buy a size one-up, but found it wasn't necessary.
Does Depends in the US/Canada offer free samples?

Good for trying them out.
