Active pelvic forwad tilt to solve pernisum and/or ass pain?

I found out cruching a little bit/activating core muscles to roll my body a bit in an round my back helps a lot to reduce load on perineum and prevents ass pain too. Tried 3 different saddle types and that seems to help most.

Is it false?

The only problem with it is, that I get more load on my hands and tricep, because I push myself a bit back into my seat. Positioning the saddle back feels wrong, then I am too steched.
