What is a guy's opinion of plastic surgery?

When you were younger? Your 18-24. Personally, that is a little over the top for me, but I guess insecurity will do terrible things. Oh well, to each their own. Like motorboater said, unless it was botched or if he is getting out a magnifying glass, he probably won't see it until you have been intimate already. By that time, a scar shouldn't scare him away. Do you need to tell him previous to intimacy? I think not. If he has a scar phobia or something, I would think a question from him would come up before intimacy. Otherwise, just enjoy the ride.

Well, unless you had a horribly botched tummy tuck I doubt your scar is repulsive.

And most guys won't care about it nor your surgery (provided you're not one of those "addicted to plastic surgery" people that keeps getting them and hates her natural look, that is kind of disturbing). But if you're satisfied with your current bod, and he likes you, then its his job to be satisfied with your current bod.

That's not to say that all guys like your current bod, or feel good about ANY plastic surgery. There are some out there that don't like your bod as-is, regardless of how great you are. Those guys will self-select away from you anyways, so don't worry. And if they don't (meaning they want you to change your bod for them) dump them.

But to find out if you're dating an anti-plastic surgery fanatic, tell him the truth early. He'll either dislike it, in which case you know to move on because you can't undo it, or he won't mind, in which case proceed.
