Has he had a full std panel done along with herpes testing to know his status or is it just assumed he has nothing?
Your genital herpes isn't going to be transmitted thru you performing oral sex on him. the two of you can discuss what precautions to use, if any, when he performs oral on you.
If the skin on his hand is intact - no open cracks, no bitten cuticles, no open cuts - his risk of contracting herpes on his hand is very, very, very low.
Personally I recommend that you take daily suppressive therapy. Have you two discussed this option at all yet?

He has done a full std check up and he is clean.
He likes me and wants to be with me but he is little uncomfortable with the whole situation as he doesn't want to get it.
So kissing and me giving him oral sex is okay and condoms during sex.
I am taking daily suppressive.
Anything else I can do to reduce the risk?
All that takes his risk down to 1%/year. Not going to get it lower than that.
If he's not comfortable with the low risk, this might not be the right relationship for you. Don't stay with him just because you hope that he'll eventually get ok with it. You deserve a full and fullfilling sexual and emotional bond with your partner and don't settle for less!
