I do not know how to avoid the numbing of one's nutz while using the trainer..After only 30 mins I am toast, numb and afraid......What to do. I use good shorts, Tri specific saddle with soft tip, and even attempt to stand at times. I hate riding the dam thing

Is it the same bike/sadle as when you're out riding in the real world?
There are a couple of possibilities:
If the trainer puts your bike at a different angle, (front wheel lower than rear) that could be the problem. (You may be more forward on the saddle than when riding on the road, putting more presure on the tender bits.)
If you're riding less hard than out on the road (less pressure on pedals means more pressure on seat)

If the saddle/bike isn't the same as the one you ride in the real world, it's possible that the saddle doesn't fit your ischia (the bones in your pelvis that are meant to take your weight).

Youll need to stand and stand early. Its normal. If you can stand every 5 minutes for about 30-45 seconds, you will prolong the numbing.

I don't think that I would call numbing normal. I can ride my indoor trainer for well over an hour without any signs of numbness. My understanding is that numbness is mostly caused by the saddle, saddle adjustment, and overall bike fit. I use a specialized toupe on my cross bike, and I have a selle italia strike on my tri bike. The specialized is more comfortable (once it broke me in), but I dont notice numbness with either one. I would suggest messing with the saddle adjustments, maybe drop the nose a little bit, and if that doesnt work, maybe a new saddle is in order.

+1. Saddles and positioning make all the difference. I can't ride a high $$ fizik arione without getting numb in minutes. I can stay seated on a trainer for 1.5 hours without pain and I weigh about 95kg right now (209), so it can be done.

Is your saddle level? I would put it slightly nose down and see if the problem goes away.

I find I hurt more if I wear my cheap bibs on the trainer.

It's the saddle. Just keep trying different ones. Specialized has some good ones. Some like only Brooks.

Id stand for 30 seconds every 10 to 15 minutes until you get your seat issues straightened out.
