Pussy Pumps any good ?

Sorry to post this here but could not see a suitable place for this post....
We like to try out most sex toys but have never tried out a pussy pump but have a few questions

Could they be dangerious to delicate tissue ?
Do they work well at increasing feeling ?
Are they best used by people who need extra stimulation ?
How long does the effect last ?
Should we get one if so which one ?

Thanks in advance

I have no experience of pussy pumps, but I have used a penis pump so I know what to avoid. Too much pressure can burst blood vessels so take it easy! Besides that I've seen pictures of women with massive pussy lips after using a pump. Not very attractive imho.

That's not to say a bit of suction doesn't feel good happycamper - you just have to avoid getting carried away, that's all. :-)

Well its off our to buy list now, thought they could be harmful thanks for the heads up .
