Post pictures of the tails and we can tell you. iPod is acting up, cant give you the link, but search (on this forum) Sexing Pics.

Same sex, same relative size, and you should be fine. Is your Pugent CB (captive bred) or WC (wild caught) and is your friends CB or WC? You wouldn't want to put CB snakes with WC ones.. They'll pass on who knows what aside from parasites.

The species will be ok together.
