would this be considered nice?

I was at my buddy's house the other day and he has a nice sized boa. We measured it at around 5'8". He feeds it twice every month (jumbo rat) because he doesnt want it to become a giant. I was wondering since its still pretty big, is it likely to be a female? Hes been feeding it like that for a while..pretty much since it was little. Sometimes, unfortunatly, he said he even feeds it only once a month.

Also would this boa be considered a nice boa, or just what majority end up looking like. Either way it was a total sweetheart and was really mellow. Real fun snake to handle, and I cant wait until mine reaches this size!!
