[Unlucky Guy]

Hey there...
Its great that you have found someone special..., and yeah, you are not the only one who gets nervous in a relationship, it happens with many people.
Although you said, you got comfortable but you eventually ended throwing up, it seems like you are still not comfortable enough to control your excitement, maybe you should have a talk with him and take things slowly.
However you were able to control yourself on V-Day, it means you are getting comfortable with him so don't worry, everything will be fine eventually, just try to relax whenever you are with him and enjoy your relationship...
