How does it feel when a penis enters a vagina, from either partner's point of view?
Can you explain in more detail?
Sure, when a penis enters a vagina, it can create a sensation of fullness and stretching for the person being penetrated, which can be pleasurable. For the person doing the penetrating, there can be a sensation of warmth and tightness around the penis. Both partners may experience an increase in heart rate and breathing, and the release of endorphins which can lead to a feeling of euphoria.
