If the man ejaculates before the woman reaches orgasm, the semen will lose the vitality of some Y sperm due to the contact of the semen with the acidic secretions in the vagina, which may increase the chance of a female fetus.
Want to have a Boy
During sexual intercourse, pay attention to regulating orgasm. Some people say, "Because your wife has an orgasm, that's why you have a boy", and that's true. Because the vagina is acidic, when a woman orgasms, the mucus secreted by the cervix is alkaline. That is, the higher the degree of orgasm a woman feels, the more alkaline secretions, and the easier it is for Y sperm to survive.

Want to have a Girl
If you want to have a girl, you should ejaculate the semen into the shallow part of the vagina, intentionally increase the difficulty of the long-distance travel of the Y sperm, so that the X sperm is far ahead and the first to combine with the egg. This is because the X sperm survives for a long time and can adapt to the acidic environment. The shallow insertion position can eliminate the Y sperm as much as possible and increase the probability of the X sperm reaching the uterus.

If you want to have a boy, ejaculate deep into the vagina during intercourse, which will help the Y sperm to appear near the cervix and avoid the difficulty of traveling long distances through the cervical mucus.
