Sexual experimenting

Hi
I hope this is the right place for this.
I am enjoying trying things. Like sexual things. I am exploring my sexuality I guess and really liking trying new things.
I have been invited to go to an adult party...... If you know what I mean. It's with I guy I trust and who has promised to look after me there. He has been before and says it is all safe and all the guys use condoms and no rudeness or pushy people are tolerated and so on.
I find the whole idea really exciting and am torn between really wanting to go and being really nervous about it all. It's seems like most of the people will be older than me too which I know shouldn't be a problem and I have been with older guys but I don't want to get there and feel too weird about it all.
Any advice from others who might have done something like this.
