!!!!!

I'm about to have sex for the first time! (I'm 21 and I've been waiting for the right guy). I haven't had much of a sexual past so this will be a first for a lot of things. He's been telling me he can't wait to make me feel good and find out what I taste like (yes I know what that all means) and I want to make him feel good in return. I'm so ready but I'm nervous to do something wrong or not know what i'm doing. Mind you he is VERY experienced. Is there anything I can do to make sure I "taste" good? And any tips on how to make sure this is pleasurable for the both of us??

Also, how does everyone feel about swallowing?? I know he likes it but that's another topic I don't have much experience with so I don't even know what to think. HELP!
