Your body is applying pressure on the padding, that will slow the process. Male or female doesn't make a lot of difference. Awhile ago northshore was getting complaints about poor wicking and leaks out the back corners while the back padding was dry. They responded by posting instructions on how to "prep" your diaper before going to bed. It basically involved folding the crotch so there was a "channel" down the middle for liquids to easily flow to the back where the crotch transitions to the back. There, it needed to be able to pool while the padding worked on wicking it under your weight.
That's a problem with almost any diaper, though the higher the SAP concentration, the worse the problem. If your diaper is stiff, that makes it harder to "get lucky" and have the diaper fall into that correct shape when you're taping up. The northshore supreme has both of those issues, the diaper is very high SAP and is also very stiff (mostly as a result of the high SAP) so you really need to do this to get good capacity out of it overnight. Also, high-sap diapers swell more when wet, so any channel you happened to have will get quite a bit smaller once wet, so you need to start out with a larger channel.
I've personally been doing this with my diapers for years. The bambino bellissimo are also poor wicking and require a channel to avoid leaks. The other thing of course is if you don't spend all night on your back, you need to roll onto your back to wet, and stay there for several minutes while the wicking does its magic. Turn back onto your side too soon and the wicking will work against you, sending liquids instead to the back corners, causing a leak. Also, with a higher-SAP diaper, once you have the back about 1/2 wet, you need to avoid floods, because it just can't wick that much rearward before you start leaking out the back corners. No amout of tightness on the lower tapes seems to be able to help much with that.
I personally know it's time to stop wetting and maybe think about getting up to change if the padding in my diaper is wet to within 1 to 2 inches of the end of the padding in the back. That's also more-or-less what I aim for most nights, a "properly used diaper" by morning.
