Womens toy question

[LeeKee]

I have a few questions for anyone with experience with a couple toys for women. I see the nipple/clit suction toys here and there. My wife and I have seen them in on line catalogs before. She expressed an interest in them. Due they work in a way to make the clit bigger, and therefore more sensitive? Also, similar question on pussy pumps. I see the resulting swelling but how doest it feel? Over all, what's the sensitivity levels after use? Thinking of try one or both. Wife and I will be visiting an old favorite sex shop, I may surprise her. Thanks for any input.
