this is pretty much no risk at all for you. you are unlikely to contract hsv2 orally from performing oral on him. Mutual masturbation is not a risk either.
are you going to continue to have a relationship with this fellow? if so we will gladly give you info on how to best protect yourself from his hsv2 :)

Low risk when is no outbreak but possible of virall shedding, where the virus live on the skin but no outbreak. So your encounter envoled unprotected oral sex but you dont have any symptoms, new infection shows symptoms after 2-3 weeks but some people its take more. Its very unlike to pass by his hand to your vagina. I guess if you infected you may have symptoms on your mouth/lips not on your genital. Take IGG herpes test after 3 months of your encounter.
I should mention that to my knowledge he did not have an outbreak at the times of these encounters.
