I experience nightfall about 5 to 7 times a month, where a white sticky liquid comes out, and I think it might be sperm. However, when I try to masturbate like most guys do, nothing comes out except urine. I also had sex with my girlfriend using a condom, but even then, I didnt feel like sperm came out. Does this mean I can have a baby?

Nightfall (nocturnal emission) is a normal phenomenon, especially during adolescence and early adulthood. The frequency you've described (5-7 times a month) is within the normal range.Regarding your concerns:_The white sticky liquid_ is likely semen, which contains sperm._Masturbation_: It's normal if nothing comes out except urine, as the body may not always produce semen during masturbation._Sex with condom_: Using a condom prevents sperm from entering the partner's body, so it's expected that you wouldn't feel sperm coming out._Fertility_: Nightfall and masturbation don't affect fertility. As long as you have normal semen production and sperm count, you can father a child.If you're concerned about your fertility or have questions, consider consulting:1. A urologist or andrologist (specialists in male reproductive health)2. A sexologist or a counselor (for guidance on sexual health and relationships)Remember, it's essential to practice safe sex and use protection to prevent sexually transmitted infections (STIs) and unintended pregnancy.
