Just because you gave and received a blow job does not mean you are bi. And just because someone is bi that doesn't mean they will give or recieve blow jobs from other men either.
There are tons of straight chicks out there that eat pussy and pop off orgasms from other chicks going down on them. and there are lots of bi chicks that don't eat pussy or don't like another woman going down on them. Just as there are straight chicks that don't give blow jobs and there are straight guys that don't eat pussy. This really isn't any different. It just isn't as socially acceptable.
Bi is if you are sexually attracted to both males and females. Are you actually attracted to males as your general orientation or were you just comfortable enough with this person to allow this to happen? My wife is straight but if she is comfortable enough with a situation she will give and receive pleasure with other women just for the extra pleasure. She doesn't really have the hots for them.
Orgasms are a physiological response to physical stimulation and will occur with the right stimulation regardless of the gender giving it. What is the deciding factor is if the recipient is comfortable enough to enjoy it and allow the response to occur.
Personally I'd probably run screaming out of the room if some guy tried to touch me but that is just my own hang up. I've seen a number of completely straight guys that couldn't even get it up with two hot chicks blowing them because they weren't comfortable in the situation. That's their hang up. I'd say you have a little advantage over them
