...Who are these people saying their husband is not "allowed" to buy a motorcycle? Do you withhold sex if he does?

I got my first motorcycle as a teenager. I am 34 and I have never been in an accident on one. Granted, that doesn't mean that it will never happen, I'm just saying it's not necessarily a disaster waiting to happen. BUT:

I always wear full protective gear (include a helmet, obviously) when I ride. All the gear all the time.

I keep my mind on the road, on traffic, and on other drivers (defensive driving goes to a whole new level when you're on a motorcycle).

I'm careful, I go at speeds I'm comfortable at, I don't show off.

I'm good. I'm not trying to brag, but it does require a certain level of skill just like anything else. Caution and responsibility will carry you a long way, but you need skill as well.

If my son met all these requirements and was willing to take a motorcycle safety class, I would let him. I would not be buying his bike for him, though.

Talk to your brother about taking a safety class and wearing protective gear.
