YES! But, then, I'm a professional photographer

and have lots of friends to do trade with. I spent early Sunday morning romping around half naked in a wet, freezing field by the side of the road for a photographer friend, and plan to do more in a studio, etc.
At the very least I would say make sure you have a friend who likes taking pictures take a lot of good ones so you'll have a record. I have been trying hard to take lots of self portraits but it is kind of a pain, so I'm hoping to do a few more shoots before my due date.
You won't regret it if you do them!
