oral sex before masturbation?

me and my girlfriend are still virgins but we planned on having sex and we're nearly at the point to where we just can't wait and i'm thinking about having oral sex, but is it alright to give my girl oral sex if she have never masturbated or is it best 2 wait until she at least masturbated 1st then give oral?

There are no rules like this

There are no rules like this to sex! Either way would be fine. Just don't push someone into doing something they don't want to do, and always wear a condom.Everything else here, all the techniques, are simply guidelines. You're still young so there's plenty of time for experimentation. It really doesn't matter whether you give her oral first or not. If you like, read the section on oral sex on the clitoris.But I'd recommend you use your fingers on her clit first, since it's simpler and more reliable.
