I exploit this forum to ask a question a little bit strange. This question derives above all from what I have read in various websites, but also from some porn scenes I've seen online. My "doubt" is about the moment of penetration (anal or vaginal is not important).
In fact, I have noticed that certain people advise to retract the foreskin altogether, so that it is completely lying on the shaft of the penis and the frenulum stretched to the max, before starting the penetration. I don't care, although it should be considered, that often already with the erection the glans is exposed or that there are various anatomical differences between boys (see length and elasticity of the foreskin).
Moreover, I know perfectly well that, except in cases of phimosis, when the penis is inside the vagina, the foreskin will go always behind and over the glans, so that it is uncovered/covered alternately and rhythmically because of the "penetration movement".
By the way, in some porn videos I see that some men begin penetration with the glans exposed, but with the foreskin only slightly behind the "corona"; other men do as I wrote above, a minority instead enter the penis into the vagina without the glans is completely uncovered.
Now, I understand that this question is not important and will probably make you laugh, but it is my curiosity (being virgin); to better express the idea, I attach a photo found on the internet...
