As someone who is highly allergic to latex and cannot take hormone based birth control, preventive measures are fairly limited. Lifestyles Skyn is the best latex free condom that I've tried. It's thin, non-textured, mostly odorless and fairly inexpensive. Skyn is made of polyisoprene and I like the feel of it much better than polyurethane condoms. Polyurethane felt plastic-y and stiff to me, while these felt much more flexible and more like very thin latex.

I've used these for years and have never had one slip or break, so durability is a plus. However, as with any condom use, there is a risk of slippage or breakage. Not only are these durable, they are stretchy and conform better to the body than polyurethane condoms. This means that they fit a wide range of men even though they only come in one size (average).

I don't think these felt as good as skin-to-skin contact, mostly because the reservoir tip is a little large and can be noticeable during sex. There are times when you can feel the reservoir tip enter the body, get bunchy during the deed, or it makes a plastic-on-plastic sound. This can usually be fixed by shifting positions. Also, the lubricant wears off rather quickly. On the plus side, the lubricant is safe for highly sensitive skin, is mostly odorless, and nearly tasteless. According to the manufacturer, these condoms are also safe with water-based or silicone-based personal lubricants, but should not be used with oil-based lubricants.

These are also safe for oral, anal, or vaginal sex. However, you may be able to taste the lubricant during oral activity and you can leave the condom without any exterior lubricant. Make sure you have a lubricant ready if this is a regular part of your play. Also, as with any good condom use, use a new condom between anal sex and vaginal or oral. This condom can also be used to cover many toys.

Despite some drawbacks, Skyn is the best experience I've found so far and most of the time I don't notice them at all. For the price, durability and overall experience, I'll be sticking with these for a while.
