In general, you should seek a position that does not cause discomfort to the woman during intercourse and, if you are seeking pregnancy, have sex on the fertile days.
On the other hand, some specialists recommend the genupectoral position and subsequent penetration to achieve a pregnancy with uterine retroversion. The explanation for this is that the deviation of the uterus is attenuated with this position and, in addition, it allows a greater opening of the cervix.
Finally, another piece of advice for these women seeking pregnancy is to keep their legs up for a few minutes after intercourse.
