Remember the following points:
Never use a condom more than once.
Only use a polyurethane condom to stop of unwanted pregnancy and transmission of STDs.
Lubricated condoms are both more comfortable and less likely to break during intercourse.
For all forms of sex use a water-based lubricants or waxaline as petroleum based lubes will rot the condom (it will flake away in little pieces).
If you are performing oral sex, a dental damn works better.
Drawbacks
As with all condoms you must interrupt foreplay momentarily to put it in. Further, Oil-based lubricants such as petroleum jelly, edible oils and medications weaken latex condoms. So again ensure your lubricats are water based.
