If it does smear or streak, you do not want it to ruin the central part of your image. You can rub the page rather hard with a kneaded eraser, because they are soft and unlikely to tear the page.

Article: Condoms are most commonly made from latex, polyurethane, nitrile, polyisoprene, or lambskin. Each has advantages and disadvantages. All should be disposed of in the same way. They go in the garbage. With condoms, there's no real way to avoid the landfill. Get a biodegradable latex condom or lambskin condom if you're worried about the earth.

Polyurethane is stronger than latex and can be made thinner. They are a suitable replacement for people with latex allergies. However, they are more brittle and expensive than latex condoms. Nitrile feels a bit like latex and is relatively inexpensive. This material works very well for female condoms. Polyisoprene is relatively new material.

A pet could bring it back inside, or try to eat it, causing health problems. Young children might play with it and become sick. They will take a very long time to breakdown. Composting condoms can also attract animals. Not only are wild animals hazardous, the condom, if ingested, can cause the animals harm. Even pets may be drawn to it.

Though there are people developing tools to do so, the technology isn't quite there yet.
