I know a woman’s vagina can stretch in width but does it also stretch in depth?
Yep! Vaginas are like tubes with walls of wrinkled tissue that lay against one another — kind of like an accordion. They can stretch to allow something to go in or out (like a tampon, finger, penis, or baby). When you’re not sexually aroused, your vagina is about two to four inches long (or deep). When you’re aroused, it can stretch to four to eight inches.
