Why do I wet the bed after masturbating?

This can happen because of the sudden increase in blood pressure, muscle tension, or changes in hormones during the activity. To help lessen these headaches, you might try taking it slower, using techniques to relax, or turning your body to a different position. If the headaches still annoy you, it's a good idea to talk about this with a doctor.

Having sexual intercourse with an HIV-infected partner without condoms is risky and may result in HIV infection. If you have had sexual intercourse with a sex worker and the condom has torn, you should test for HIV as well as other STIs as soon as possible. 

Quite often, a person will irritate a temporary malfunctioning of the excretory system due to too frequent or too expressive self-fondling. Such issues as sharp pain during urination can come from slight inflammation or muscle tension in the area. It is important to take care of yourself by keeping well-hydrated, not overdoing it, and letting your body rest. 

The risk of pregnancy from pre-ejaculation fluid outside the vagina is very low (but not impossible). The sky-high record for the lower cases of late periods your wife is facing could be of various reasons like mental stress, hormonal imbalance, or many other factors. Diving this into a regression, I recommend a pregnancy test to take a break from the worries. Be sure to use contraception methods in the future to avoid any troubles.

The sperm was not ejaculated in her and, apart from that, a condom was used, thus the likelihood of pregnancy is very small. During the menstrual cycle, it is always more difficult to become pregnant. However, do not forget that no method is 100% sure. If there is any unexpected symptoms or she has a missed period, the pregnancy test will be the best option to verify.

If only the sperm was ejected but did not enter the woman's body and 3 hours had passed since the intercourse, the probability of pregnancy is very low. Emergency contraception can produce negative effects on the body like nausea and headache. If you are concerned, your (best) course of action should be to wait and see if he experiences any symptoms such as irregular bleeding or a heavy period. Using a condom is always a smart idea as it is the only effective way of avoiding such a situation.
