Any other 'leakers'? Any tips?

It's actually so annoying, I leak A LOT. I really hate that feeling when you have a piss and 'flex', and a bit of precum comes out at the end, and it still feels like there's more to come. It makes the time you take in a toilet 5x.

I got a few hundred condoms of aliexpress so I use them all the time, lot less messy that way. But does anyone have any other tips?

The most absorbent = diapers, then you don't have to worry at all and much lest spent time on the toilet.
If not your kink, then you may just use some woman hygiene products like small pads or even a cloth or paper tissue. Just make sure that the paper tissue does not dissolve like toilet paper when wet. Regarding woman hygiene pads they sell then all over the place and you may go cheap and just an insert will helt with the after dribble and precum.

Or find a solutions that works for you and I hope that some of my tips helps on finding it.

Search adult training pants and go for the thickest they have. Most of them are marketed for the abdl community, but it will help you the same.

I'm an ab/dl so I'm usually in diapers anyway. So no problem with leaking and dribbling.
