Many modern seats have a relief area in the middle to prevent that. However if you are pulling the 25 year old road bike out of storage to ride again, you'll want to change the seat. And the tires, bars, brake pads, etc. Actually seats are referred to as saddles in the catalogs but I can't get in the habit of calling them that."In men, a sheath in the perineum, called Alcock's canal, contains an artery and a nerve that supply the male sex organ with blood and sensation. The canal runs along the side of a bone, Dr. Goldstein said, and when a cyclist sits hard on a narrow saddle, the artery and the nerve are compressed. Over time, a reduction of blood flow can mean that there is not enough pressure to achieve full erection."
