It hurts. A lot.
If you're expecting to whip your little man out and plough straight in you're sadly mistaken, or you're going to have a girl in agony very quickly.
For a first time it takes a lot of lube, and a lot of time.
As for Anal orgasms, not unheard of but I'd be very surprised if someone doing anal for the first time had one
Ok gently does it then. You see sometimes girls have told me that they are virgins when they really aren't but this one i think is the real deal and it might be too much too soon for DHUTWU.
Very gently
And you probably want to get her "warmed up" first with some foreplay (if she'll let you do that... can you do anything round the front with her?)
It'll probably hurt you too by the way.
Yes man I love going down on a woman so that's not a problem. If it's going to hurt us both why is this so revered? Probably have to find that out myself but thanks for the tips which I will use.
