Where to buy personal lubricant?

I know, it's an embarrasing question, but I am looking for personal lubricant, basic KY jelly is fine by me. I know where to look, at a Walgreens or a CVS, however, when I walk in I end up walking around for ages, not being able to locate any. I ped some for women in my Walgreens...which for some reason was located in the dental health section. It was a whopping thirty bucks though! And I'm a guy, I don't want the woman's stuff. Looking around it I found nothing but toothepaste and mouthwash, so where in a Walgreens or CVS would I find some? I certainly don't want to ask...that's embarrasing to me...since I'm only 16.
