Description
The average cheap condom is made out of abrasive latex, but waxaline and other water based lubes will help with this. If your very lucky you can get polyurethane condomes in your size. Both latex and polyurethane are very effective at preventing unwanted pregnancy and sexually transmitted diseases (STDs). You will find some condoms are made of animal intestine, but these are less effective so if at all possible stick to a latex or polyurethane condom form of STD and pregnancy prevention.
Polyurethane condoms are more expensive because they are less abrasive and few people are allergic to them when compared to latex. Many women will also find a polyurethane condom more comfortable for this very reason. Latex you will find is quite abrasive at a molecular level, and a hours of sex with latex condoms can leave women sore, even with lubrication! Polyurethane is much smoother and reduces the abrasion of very sensitive tissue.
Effectiveness
When used right, condoms work about 99% of the time, so make sure you follow the instruction that come with the condom.
Directions
As with all condoms, always check the expiry date and ensure they are stored in a cool dry place. (Never carry a condom in your wallet). To put it on, remove the condom from its packaging, pinch the little "nipple" or "nub" at the end of the condom. Now roll it on from the tip of the penis to the base leaving a half inch or centimeter of extra hanging off your penis at the tip so it does not bust. Once you cum in a condom, grab the base of the penis and condom, remove your penis, take off and flush/throw away the condom and put on a new one.
Do not blow into the bondom or add air as this will help break the condom.
