WB doesn't do testoterone, most of us are either to old for that or just don't feel the need to always be in front of the bike in front. i ride like miss daisy most of the time, anything like rossi and i find it spoils the ride out as you miss loads of stuff.
don't worry about being the new one on a ride out we have all been there, everyone rides with consideration and no one gets left behind.
we had a newbie last year with the same concerns having only passed their test weeks earlier and within 30 minutes they were at the front of "the pack" and thoroughly enjoyed their first ride out
so don't be backward on the first ride out (weather permitting) you will not feel like an oddball. (unless of course you want to be an oddball)
