I think age even has a little to do with it for some. 10 or so years ago when I switched from just being a leisurely ride around the neighborhood a few times a month to riding 4 to 6 days or more per week for fitness, my butt was sore for quite a while. Something on the order of weeks for the major annoyance.

I was riding the same bike that was comfortable to me back when I was a teenager, so I knew it wasn't the bike. It was my butt being over 50 and out of riding condition. I rode anyway. I played the Swap Saddle Game which seemed to help, but finally wound up with a saddle that wasn't too different than the one that was on it when I started the saddle swap game.

Even today, if I lay off riding the bike for a couple weeks and then start doing long rides again. I'll get a little annoying muscle and joint pain around my sit bones and maybe my tail bone, but it doesn't last but a few days at the most now. And it's not anything that I'd even complain about to others.

Most of the bikes sold today have decent seats for their intended use. Rarely, there are people that have pelvis that put their sit bones outside the norms. Some bike shops can help you figure it out or just google for "sit bones bicycle seat sizing".

If you are new to cycling and you only do a ride every week or so, you'll probably constantly be plagued with butt soreness.

But remember, this is IMO. And based solely on my perception of things that may or may not have been a factor for me. Along with a little reading that I may or may not have understood fully.

1) Your sore butt is a sign of a person who hasn't been riding. This is the most likely. The cure is to ride every day if you can, but only for 30 minutes. 2 weeks of that will pretty much take care of it. Unless:
2) The saddle is too soft or too hard or too narrow. You want a saddle that's not hard as a board, but yet not squishy. You should be able to depress your thumb into the padding, but not have it sink very far. If your sit bones are on or near the edge of the saddle, it's too narrow. Bike shops can measure your butt and recommend a proper width saddle. However, #1 is more common.
