In my case, it is probably a mix of not getting much riding time in for a while (I started college this fall), and being confined to the saddle for extended periods of time. You have to remember that when on the road you can get out of the saddle and relieve some of the discomfort. My advice is just to suffer through the pain; after all, suffering is an integral part of cycling. You will gradually be able to endure more and more.
Good Luck

Suffering is not the same as hurting yourself.

Maybe it's time to go to the gym or run outside.
Stand up every few minutes helps. Challenge on rollers! nmSpunout

Is your front wheel set up on a block or phone book? If not, you're riding "down hill" and your boys are sliding forward on the saddle. Make sure your bike is level or even slightly elevated.
I had same problem, did three thingsContinental

1. Raise front wheel to be level with back.

2. Shift around on the saddle, especially sitting with weight on the rear of the saddle.

3. Frequently change resistance. Increase resistance for a few seconds every few minutes to get more weight on pedals and less on seat.

When the 'boys' go numb, it's not something to just ride through as one other person responded. It's a very strong indication that you are compressing the penile artery, and possible nerve bundles that run between the 'sit bones'.

I suffered from this real bad when I first started riding. I'm on the thin side, and don't have a 'big ass' to support me on the saddle so the saddle compressed between the sit bones.

I went through more than a handful of saddles, and worked hard on attaining a very good fit to the bike. I now never get numb. Spent 1.5hours on the Computrainer yesterday with 99% in the saddle and no numbness.

My suggestion .... first make sure you've got a good fit to your bike. Lots of web sites to help with that, or better yet go to your LBS as they can place you on a trainer and observe in addition to just doing computations.

Then, work on a saddle that works for you. Some like cut-outs in the back, some like cut-outs in the middle, some like totally split saddles.

Personally, I found the San Marco Aspide Arrowhead to be the solution. However, after 40 miles it's a bit of torture device as it has almost zero padding. This week I've been riding on the Specialized Ergo saddle (weighs a ton, and has lots of padding). Not quite as good as the Aspide but it might be my choice for rides in the 50+ mile range.

At this point I've lost track of how many saddles I've tried. Unfortunately, I never return them as it's such a hassle to find time to get to the shop. But, I think finding that proverbial saddle is worth the cost and effort.

i've found that i have to change my saddle position slightly..._rt_

when i'm on my trainer to maintain comfort. granted i'm a girl so i don't have any boys to go numb but discomfort is discomfort!

on my trainer bike the nose of my saddle is pointed up slightly higher than the nose of my saddle on my bike that i ride outdoors. riding the trainer i move around on my saddle less and stand less often.

if you can, try playing around with your saddle position some.

Part of the issue is that you're not pushing as hard on the trainer as you are on the road. Every time you push down on the pedals, you're lifting slightly. Since you're sitting there toodling along, all of your weight is on a spot that doesn't like it!

Another part of the equation is you're not moving around as much. Since the trainer is supporting your bicycle, you don't need to shift your weight around to avoid things, etc.

Pedal easy, crotch goes numb. Go hard, no problem.

The solution is to stand, move, and mimic riding outside as much as possible. Do that and the numbness should go away.

That my opinion, and I'm sticking to it!

You can go 5 minutes? It takes me only 3 to get numbNatC

I think it's because you just "plant it" like a sack of flour when on a trainer, whereas a real ride is more dynamic since you're moving the bike around beneath you.
