Jelq sitting V.S. Jelq Standing

Will it make any differences?

When I jelq standing for a long time, my legs feel numb.. So I sit.
I wonder is it ok doing it while I’m sitting?
Does sitting make the blood flow any less or something?

Thank you!

There’s not a big difference between standing or sitting on the edge of a chair. The only advantage of standing is that you walk around the room if you wish.

I mostly do mine sitting. I find I can concentrate more on the sensations in my dick and what’s going on around it. However sometimes I want to see what it looks like so I’ll do some standing to take a look at myself in the full length mirror.
