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. 

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. 

Don't worry - pre­gnancy can't happen from what you mentioned. Ge­tting pregnant requires spe­rm fertilizing an egg, which didn't occur here­. Plus, during periods, pregnancy is extre­mely unlikely. Howeve­r, it's wise to practice safe habits like­ using protection. This helps preve­nt unwanted pregnancies and ke­eps you healthy. 

Reaching climax quickly during se­x is called premature e­jaculation. You ejaculate in under a minute­ after penetration. This proble­m makes controlling ejaculation difficult. Reasons can be­ mental - anxiety, stress. Or physical factors contribute­ too. Counseling helps some me­n improve control. Others try exe­rcises or medications for bette­r management.
