Honestly, the only person who can tell you whether or not you should get it done or not is yourself.
If by not getting it done you will have low-esteem or other problem, then that's not going to work too well.
- In either scenario, if a girl kicks up a fuss about it she probably isnt worth your time.
If it's not a self-esteem issue, then treat the operation as one of last resort. Expense aside and hassle aside, there really isnt that much going for it at the moment. Unless you intent to be getting stuff in America where it's the supposed norm, but even there the proportions are dropping.
Once you get it done, there isn't really any going back. That's probably the most important point.
