I was wondering if anyone has any experience with vaginal pumps.  This is a bit embarassing but I had a cheap little one a few years back but it never fit snugly to my lady parts and I couldn't get good suction.  I am a chubby gal and ummm, well so is my nether-regions' lol. 

It's sad because I used to be able to cum quite quickly.  But since my boyfriend has difficulties getting and maintaining an erection it is causing me anxiety....anyways, I was wondering if the pump would help make me more sensitive.  Any ideas, thoughts, or experiences?
