Why does a trained pelvic floor improve sex for women

A well-trained pelvic floor not only enhances sensitivity but also provides “mechanical” benefits during sex. This is mainly because the pelvic floor muscles contract and the vagina narrows during intercourse. As a result, both partners experience more intense sensations. In contrast, weak pelvic floor muscles lead to weaker contractions and therefore less narrowing of the vagina. This means that partners feel each other less strongly and sexual stimulation becomes more difficult.
