a new bike and a numb groin

Early Saturday morning, I took my new Felt Z35 out for a 24-mile ride. Now, four days later, I'm still feeling the lingering effects of a numb groin. Not as bad as Saturday afternoon's "can't feel a thing" but definitely not back to normal sensitivity.

Turns out this condition is technically referred to as "perineal symptoms" and there's been a lot of content around it thanks to commercial development of seats designed to relieve pressure on the perineal area.

I'm not yet ready to invest in a new saddle, so I've been looking around at what the Google has to offer in response to "bike perineal symptoms" and trying not to get scared of all the ED mentions alongside the perineal symptoms.

The best advice I've seen so far is an article over on about Groin Numbness and Bike Riding where they give the following recommendation on how to prevent perineal symptoms:
    1. Stand up frequently on the pedals to take pressure off the perineum.

    2. Change your position on the saddle while biking. Shift forward and backward when you ride to eliminate pressure on just one part of the perineum.

    3. Experiment with adjusting the angle of your saddle so that it tilts slightly downward.

    4. Wear bike shorts. They have chamois padding in the perineal area that will help relieve pressure.

    5. Adjust the height of your handlebars slightly until you find a comfortable position. Handlebars below the saddle may work well for road or racing bikes, but perhaps not as well for touring or hybrids.

    6. Make sure that your seat post is adjusted to the proper height. Your knee should be just slightly bent at the bottom of the pedal cycle.

    7. Limit the number of miles that you pedal. This may not be desirable for all riders, but number of miles per week can be a factor.
I'll give items 1-3 a try next time out and report back on my results.

UPDATE: Great to see The Climb blog over on tackling this "intimacy numbness" issue today. Great content in the comments so far, especially the link to this Bicycling Magazine story debunking the link between saddle time and ED.

Careful of tilting your saddle downward too much. The guys at my local bike store do fittings and have mentioned that too much forward tilt can cause prolems in other areas by putting unwanted pressure on your shoulders, back, Something about losing some support that would cause the rider to compensate by leaning forward too heavy on the front half??

It's the first thing I thought of when I was having this problem. I'm getting more comfortable now. I think you just have to get your calouses built up.

Thanks for the comment, Jenni.

You're reinforcing what others have said, and I'll only do a minor tilt to see what happens.

I'm eligible for a custom fitting at the place I bought the bike (the Bike Connection in Palo Alto, CA) but they recommend I get in a hundred miles or so to get a feel for the thing.

Here's hoping the callouses come quickly! It seem the Europeans call this "finding your seat," which sounds so much more polite, but doesn't really brace the newbie for what to expect.
