I want to get fucked, but I'm afraid to at the same time... Any advice?
Well, just make sure you do it with someone you trust and that will take care of you and not just shove it in there. Using a lot of lube and wearing a condom makes the penetration easier.
Make sure you have passed stool beforehand and are clean.
Anal is painful at first, but if you get through it, it feels fine.
