You can't. In fact, the man does not even need to ejaculate inside the woman for her to get pregnant, the moment penetration occurs, you run the risk of getting pregnant. Luckily, there are several methods of Birth Control available, from the pill to condoms to even abstinence. I suggest you try some these.
The opening to the urethra is on the outside and the semen is inside you so no, that is physically impossible.
No you cant get pregnant this way.
It does wash out after a soak or use the prewash function on a washing machine then wash on a 40 degree wash as usual. Thick semen stains may take a scrub before washing. I have never had a problem getting them free from any fabrics.
Wash them.
Wash in a machine as with most clothing on a suitable cycle.
Most of it does. However, it can leave stains.
Yes.

To remove semen stains from sheets, start by soaking the affected area in cold water for 15-30 minutes. Then, wash the sheets in the hottest water recommended on the care label using an enzyme-based laundry detergent. Avoid using hot water, as this can set the stain. Repeat the process if needed before drying.
No u should always wash it before and after:d
