Transsexual
Welcome to our world honey. Next to a hard man, a clean man is good to find...
Unless you are hanging out with crackhead hoes with oozing ulcerated open sores or Herpes blisters onthier lips it's highly unlikely you are going to catch any skin born disease from a sex partner. There is some risk to living a full life.
However your request is reasonable. I don't think any quality girl is going to refuse a CBJ. That says you are concerned and willing to protect both parties.
However no skin to skin contact may be more difficult. About the only way I can figure you could do it would be for the girl to wear gloves, or for you to leave your pants on and apply a condom yourself and she would just do her "job" around the zipper so to speak.
And no I don't see it as a rude request, it's your party honey.
Have fun, and no touching...
Giggle,
TS Jamie
