A member asked:

What portion of penis should be inserted into vagina during intercourse to get positive chance of pregnancy?

The head: As long as the head of your partner's penis is inserted into your vagina and he ejaculates into your vagina, then the chance of pregnancy is high if you are having intercourse in the mid-cycle of your period when the egg comes out of the ovary.

Usually all the way: Glans has to be inserted. Sperm needs to pass through the cervix, then body of the uterus in order to reach fallopian tubes where insemination takes place. Thus ideally penis should be inserted as far as it will go, unless the the penis is monstrous long , then just insert for full length of vagina, if full unsertion is painful.

Here are some ...: Theoretically, the deeper, the better. since such inseminates closer to cervix. In reality, it doesn't matter as long as ejaculation takes place inside vagina. Sexually and anatomically, the friction of the outer half of penis and vagina, which is tighter and more sensitive leading to enjoy more pleasure and ejaculate easier. So, apply these to enjoy sex and procreate. Best luck...
