I've found that if I sit and spin for five miles or so, my um... tender parts start to fall asleep. Does this mean I have the saddle tilted to far forward/back? Or maybe just need a different one that fits me better? I'm a really thin guy, and I'm using a saddle designed for a woman, since it's technically my wife's bike, but is that even an issue?

Hard to say. Saddles are hit and miss and a big investment until you find what works. Or at least it has been for me. How long have you been riding?? Most new folks to riding I remind them you have to ride and build your arse up like a callus.

The gender of the seat is usually marketing. If the seat is appropriate width, regardless of guy or girl, then go with it. Try tilting it to the front and see how it feels. If that overloads your hands, back it off a little. If that doesn't help, get some more seat time

I just picked up a new saddle just because my stock seat was hard as a rock which was bothersome at times. If you don't like the feel, don't ride it. As far as tilt, my buddy actually let me ride his old Schwinn and I could definitely tell his seat was angled up alot. Every time I tried to sit down on it I slid towards the back of the seat, so I assume if you have that happen you are angled to far up and if the latter happens (Sliding towards the handlebars) you are angled to forward. I don't think there is a standard for Tilt or saddle comfort, considering everyone's rear is different.

Seems like I have read that numbness in the privates can be caused by poor blood circulation, or pressure on a nerve in this area. You might look at Sheldon Browns site for info on saddle adjusting and fitting.

Find a seat with a deep groove, be sure you sit far enough back on the seat and get out of the saddle more.

Reviews say the Rocket V is great for smaller/thinner people like me, so I ordered OE takeoff from eBay. I'll try to take road ride soon to see how it does (crosses fingers).

I'm a slender guy. Love my Rocket V

I had this problem. FIxed it by doing 3 things. 1) Make sure your saddle is wide enough so your sit bones actually make contact with the widest part of the saddle in the back instead of having the soft inner tissue rub the sides of the nose----unless you are a skinny racer type, try using a "women specific" saddle--which are wider and painted a different color but are otherwise the same as men's saddle; 2) make sure your saddle is leveled or tilted down just a tad; 3) learn to "dip your hips" or "spill your pelvis" when riding so that your weight is distributed between your arms and the back side of your sit bones.

sitting upright and bent over on a narrow saddle that is tilted up is a recipe for numbness in the nether regions.

No, that is a completely separate issue. If your butt hurts after a ride, just riding more (well, not that day, but I mean going on more rides) can help, though it's hard to say - sometimes you need a better saddle, sometimes you need to just break your butt in. When I used to not ride over the winter, my but would hurt the first few rides every year, but then would be fine after that.

But if you're experience pain or numbness in "sensitive areas", more riding isn't going to help. Your butt has breakin, and is designed to have weight on it. Other...more sensitive, soft tissue areas are not.

I got my new saddle in last Friday, and while I haven't been on a longish type road ride yet, I have mixed feelings initially. It feels as hard as a rock and is definitely something to get used to. This may be simply because I need to get a "callus" as BurNotice puts it; here's hoping. On the other hand, it seems to have completely taken the pressure off of the softer tissue up front, so I doubt I'll have any more numbness issues.
