i would say its definately a boy - although im no expert!

we didnt want to find out what we were having but at our 19 week ultrasound we were "flashed" very obviously by some suspected boy bits. there are some wonderful ultrasound galleries at aboutpregnancydotcom and by comparison we are pretty sure our bub will be a boy.

your bits and our bits look the same... (we never had oursconfirmed by the sonographer though)
