The uptilt that will comfortably let you sit in the right place is just a little bit below the uptilt that focuses too much pressure on the front of my undercarriage. You might need to make fine adjustments to the up-down, as well. Abrasion is for me usually caused by the saddle being too high, so my hips rock as my legs each stretch down once each cycle. When you get the uptilt correct, it's worth a try to reduce the height by just a few (2) millimeters to reduce pressure on the sitbones and surrounding areas.
You might also be pulled forward by having your bars too far forward as your saddle is moved back bit by bit. You should be able to feel in balance on the saddle, holding your hands on the bars without pushing down to hold your torso up. This stability is the result of good fore aft balance combined with good core strength. Your arms should be stuck out forward, but not stretched uncomfortably far.
