Dude!! You have to get over the "embarrassment". It's all in your head and whatever embarrassing thoughts you are having are bullshit. Deep down you know this is true. Just because your buying vaseline nobody is going to assume your using it to slick up your dick. It has many other uses as well such as treating minor burns, skin chafing and dryness etc., etc., etc. If anyone asks, which I doubt they will, just tell them that the soles of your feet(and this is true in my case) are heavily calloused and that the skin is peeling from the dryness. I'd hate to see you give up vaseline as a lube for jelqing because as I, DLD, and many others will attest to, it's the best all around lube you can get.
