Cute frog & a very nice pic! Go ahead & name the little bugger. You may never know its sex for certain, so pick a sex & go from there. Males will occassionally call & tend to develop black patches on their chins during mating season, which is called a "beard". But even then, females can also have a light beard & not all frogs will call. So unless you're planning to breed it, I wouldn't worry too much about the sex.
