Why are nocturnal emissions and masturbation problematic for me?

First things first – masturbation won’t affect your chances of having children later on in life. It’s normal and won’t hurt your fertility at all. If you’re ever worried about your health or ability to have kids, it’s best to talk to a doctor who can give you accurate information and help calm your fears. 

I get your fear but I can tell you now that your girlfriend can’t get pregnant from what you’ve said. For pregnancy to occur, sperm needs to fertilize an egg which usually happens during unprotected sex. There might be a small number of sperm in pre-cum but the likelihood of conception taking place in the situation that was explained is very minimal. It would be best if both of you do not want any STIs or pregnancies, and use condoms or any other forms of protection available. 

A small penis during an erection does not mean that pregnancy is impossible. Fertility is not related to size. Blocked canals and hormonal imbalances can cause smaller genitals. Consult a specialist for advice and support. Remember, concerns about size are common but often based on misconceptions. 

You se­em worried after unprote­cted intimacy. Unusual discharge, burning urination, sores, itching – the­se are common signs. Sexually transmitte­d diseases result from bacte­ria or viruses transmitted through sexual contact. Ge­tting tested is crucial, it checks for pre­sence of STDs, ensuring prope­r treatment if require­d.

I'm glad you've been practicing safe sex by using PEP. The risk of HIV infection through oral sex is mostly low, and when no ejaculation is present in the mouth, the risk becomes too small. However, following the doctor's instructions to continue PEP is still very crucial. Look for some symptoms such as flu-like illness, fever, or body aches, and be alert. Almost like a way to go, keep on track, and be positive with the PEP (treatment) regime.

Nightfall or wet dreams are normal for a teenage boy. This is your body's method of discharging the extra fluids. Symptoms include having an ejaculation during sleep without being in control. Causes can be hormones or sexual thoughts. To help, you might consider calming activities before bed and avoiding spicy food. 

You're suffering from some problems with getting and holding an erection. This is known as Erectile Dysfunction. Though you are, in general, healthy you may have this issue because you have advanced in age as a man. Sildenafil being a great choice which is much better to use often gives erections. The medicine is for sale at the pharmacy and must be prescribed by a doctor. Still, a primary doctor is necessary to examine and get proper advice on whether it is safe for you to take the medication.

HIV spreads through unprote­cted sex - a virus with potential symptoms like­ flu. Fever, fatigue, the­se may occur. Testing provides the­ truth, so that's wise.

Herpes is a common virus that can be passed on through skin-to-skin contact such as sex. Symptoms may include sores, itching, and pain. Condoms and dental dams should still be used during sexual intercourse or oral sex even if your partner does not show any signs of the illness. Communication with your partner is crucial so don’t hesitate to discuss any worries or questions openly with them. 

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.
