TaeKwondo?

I am looking for alternative forms of exercise, so the guy I am starting to date is really into Taekwondo and really likes it, my main concern is that I have the lapband which means I have a port attached to my stomach wall and with losing lots of weight it is more exposed. So, any suggestions and if you do Taekwondo how do you like it and how has it helped with exercise?  Kelli
