Cycling bibs question

So I’m as part time a cyclist as possible (I only really turn to the bike when I’m taking a break from running).

I’ve been looking into making my cycling experience a bit better and the general consensus seems to be that bibs are the way to go.

At the minute I’m unable to get past the whole commando thing - mainly because I can’t stand the idea of my shit flying about without underpants.

So this is a question for the guys… how do cycling bibs ‘fit’ around that area? Are they as uncomfortable as I imagine, or are they nice and snug and keep everything tucked together?

EDIT: I decided to buy some cycling shorts (made the most sense as a beginner cyclist). Went for my first commando ride today (completed approx 20km) and it was absolutely fine!
