I guess it would depend lotion what type of lotion you use, but I wouldn't recommend anal only because lotions will burn the anus because of the sensitivity of the tissues, just like getting lotion in the head of your penis or for a female, vagina.
There are certain chemicals in the lotion that will cause irritation and burning in the anal. I'd advise you to use vaseline if you need a lube, for it's much better. It can be used for the anus as it's mild and helps keep lotion lubricated.
But you shouldn't need it, for I'd recommend using a condom as there are bacterias and germs that can handjob torero you to contract a Urinary Tract Infection. Plus, it's certainly possible to get feces on your penis because feces is ejected there.
Is it safe to use moisturizer as anal lube?
Be sure that both you and she are ready for anal sex, as it's much more painful than vaginal sex. Lube must be gentle as not to tear anything or injure the sphincter. Be aware of her feelings and pleasure and not only yours. I'd advise you to wait a little while as 15 is sort of young, but it's up to you.
