1st time

So i guess im bisexual. I want to try giving my gf head. I dont mind I definitely want to do it. But sexually i get so shy. Im sexy as hell when im having sex my reactions my enthusiasm all that. But even when i first started giving men head i was nervous bc i want it to be good. And im not aggressive when giving pleasure im very reserved with touching if that makes sense. (She says she doesnt care if i ever do bc she really doesnt want it of need it) but i at least wanted to get some toys like a clit stimulater for her or something. Any suggestions or tips
