I much prefer a young fit girl who's skillful and rehearsed than an older chubby lady in their 40's who's skills are average and not rehearsed...??
Man, after I typed that I realized that comparison doesn't make any sense! :
I guess if you don't like girls who give you a massage, lick your entire body, lick your asshole, give you a sloppy blowjob (cim if you like), and are vocal during sex, then you wouldn't like these young girls...
