My boyfriend and I have sex often, and when we do we use a condom as often as possible. But when we go to get condoms there are so many to choose from! There are ribbed ones, spermicidal, ones that are specified for "her" pleasure and vice versa, ultra thin..and more. What is the difference in all of these? Do any of them really give more pleasure or feel any better than a plain lubricated condom?
