Can I touch my girlfriend's vagina on period?

Nightfall is when you masturbate while sleeping. Moreover, it is quite common among teenagers in particular. Nevertheless, it can be either stress, joy, or not having an ejaculation. Make sure you are deeply focused on the deep breathing exercise. Talking to a doctor who can guide you is also helpful. 

Some me­n face erectile­ dysfunction. They can't get an ere­ction when desired. It might re­late to health issues. He­art disease, diabete­s, and hypertension impact it. Stress also impacts e­rections negatively. Exe­rcise and nutrition improve male se­xual health. Medicines and the­rapy often help too. Talk to doctors to solve it appropriate­ly.

Let me reassure you that the situation you described doesn't typically lead to pregnancy. For pregnancy to occur, there needs to be direct contact between sperm and the vagina. The strain you mentioned getting on your pants near the zipper is unlikely to cause pregnancy. However, for peace of mind, you may want to consider taking a pregnancy test if you experience any unusual symptoms or missed periods. 

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.
