Doing testing of new SQlab 610 Active Fitness saddle. It has sort of a shelf for sit-bone area with scooped-out perineal area & the nose is rec'd to be kept horizontal (or perhaps tilted up very slightly). Furthest ride so far is 40 km, the design seems to be quite kind to perineal area. Fietsbob rec's to tilt hips back a bit, that might certainly work fine for many people; OTOH isn't hips-forward (apart from saddles) the more ergonomic style? IE in weightlifting one is supposed to keep hips forward; also the better racers I see usually seem to keep hips forward.

On harder efforts or after a fair # of kms I find the lower back wants to curl up & I try to fight that to minimize lower-back strain. SQlab 610 takes a bit of getting used to, one has to remember to sit fairly far back to keep on the comfy "shelf". Weird thing is that the saddle seems to encourage hip-forward style, doing that seems to feel more comfortable & stable. Don't know if SQlab did this on purpose but I like it.

SQlab bit about how their saddles are designed to avoid perineum pressure:
