Why do I experience premature ejaculation at 45?

Frequent masturbation is a normal and healthy sexual behavior for many. It doesn't cause any significant harm or affect your future sex life. However excessive masturbation can lead to physical and emotional health problems, such as fatigue, anxiety, depression, and loss of interest in sexual activity. You can try to redirect your sexual energy into exercising or hobbies, and establish healthy routines and sleep patterns. 

It sounds like you may have caught a virus called herpes. Herpes can cause flu-like symptoms, swollen lips, and red pimples on the penis. It is usually spread through sexual contact. To help with the symptoms, you can take pain relievers and use cold packs on your lip. Make sure to talk to your girlfriend so she can get checked too.

With HIV, which is the virus that causes AIDS, it is difficult to get it by having oral sex with someone. Some signs that someone might have HIV include feeling like you have the flu, being very tired, or having swelling in your glands. During vaginal intercourse, a condom should be used so as not to catch HIV. 

Nightfall, or nocturnal emission, is a common occurrence in both men and women at the same time. In females, it is the body's way of releasing extra fluid. Nightfall will not affect your health or sex drive in any way. A nightfall patient will still be interested in sex after marriage. It's so natural. Just keep on living a healthy lifestyle, and all will be well.

It’s possible to get pregnant from pre-cum. Pre-ejaculatory fluid may have sperm, which can cause pregnancy. If you want pregnancy to be prevented, then it is good to use protection every time you have sex. You can use condoms or birth control pills as other safe options.
