Some men like condoms that aren't as tight-fitting as latex condoms. They say looser condoms feel better. Plastic is a very strong material, so plastic condoms may not rip or tear as easily as latex condoms. Many couples complain that condoms tear when they try to put them on, or that they break during sex. They feel condoms are just not worth this trouble.
Tests comparing the durability of latex and plastic condoms are under way now.
Plastic condoms can stand up to oil-based lubricants. One of the main reasons latex condoms break is because couples use oil-based lubricants like Vaseline, vegetable oil, mineral oil, massage oil, or even butter to make the condom slide better. These oils make latex condoms weak and they break more easily. Plastic condoms are resistant to these effects. Plastic condoms can be kept longer without breaking down in heat or cold.
