So FI keeps bringing up BJ's more and more. I want to try it but i'm more afraid I won't be good at it. Tips? Tricks? 

I think the best advice out there is to just be enthusiastic. If you go in to it dreading it and not wanting to, he will be able to tell and it won't be as fun for either of you!

How about this- blindfold him, and tell him that you're going to surprise him, but the rules are he has to guess what you're going to do each time- odds are he's going to "guess" what he wants out of you, and help you along the way!

get creative, it doesnt always need to be all or nothing, kinda like teasing him before you give it your all i know dh likes that

Ditto about be enthusiastic about it. Make sure you show him that you WANT to please him!

Also, make a ring with your fingers and you use that simultaneously with your mouth. Your guy will love it!

I really wouldn't worry about being bad at it - unless you bite him, I highly highly doubt your guy will think you're bad at it :)

Eye contact! Don't worry about being good or bad. It's kinda like sucking on a big popsicle in 90 degree weather.

Agree! Enthusiasm is key! I will never forget right before I gave my ex oral for the first time I asked my best friend who is basically my older sister how to do it, and she said imagine you're licking an ice cream cone. Sounds weird, but it works!

Use your tongue and be sure to use your hand a bit as well. Confidence is sexy, so remember to keep eye contact! :)

I used googled and read many blogs and got lots of helpful tips and tricks. Confidence helps and I think the more you want to do it the better. Watch his face and listen to his moans and groans - that's when you know you're doing something he likes! Or just plain out ask him to tell you if he's enjoying it or what it is that he likes.

from a man's perspective (i'm assuming) there can't be a bad BJ unless you flat out bit him! Just having his woman/SO attempt to do it is a turn on (i would think)

Lots of lube(saliva)....noises....eye contact.  Enjoy it.  :-)
