FTR, as mentioned fit the saddle position to suit your legs and put power to the pedals. THEN if you want a more compact or upright position bring the bars back and/or up.

And finally some of us, me included, just seem to have skinny butts or are built slightly different. In my case I found that there was no way to avoid the soft tissue pressure without setting the saddle up with a few degrees of nose down angle. You may want to try the same after you move the saddle back a little on the rails. But for now leave the post turned around.

A decent enough rule of thumb is that you want the saddle placed so that when the pedals are at 3 and 9 oclock that the front of your knee is pretty much lined up directly above the pedal axis. Some small variation is possible from there but I'd start with that. If you find that pedalling the bike is pushing you back or you seem to be lifting and moving forward alter the saddle position SLIGHTLY to compensate. Forward if you seem to be getting pushed back and slightly to the rear if you seem to be pushing "back" with your feet and feel like you're falling forward.

I notice that this is also a road bike. If you're trying to ride in the drops then it's pretty hard to lean forward in that manner and NOT get pressure on the tender parts if you're actually resting in the saddle. The more aggresive "in the drops" position is generally connected with aggresive power to the pedals. Or at least the rider should be taking a lot of his weight on the legs if coasting or cruising in that position. Save actually SITTING on the saddle for when you're up on the tops.
