t need to worry about that.
What you
do need
to do is taking all possible precautions against having another
concussion, ever, because it sounds like the one you just had was pretty severe. If you are playing contact sports, or if you have dangerous hobbies, it might be time to reconsider that. But you can have all the sex you want. Even if an orgasm immediately after a concussion is inadvisable (and it probably is), two weeks is long enough to wait. You can stop feeling guilty.
