Not necessarily tighter. But a different type of tight. With vaginal sex, yung tightness is felt all over the penis (depends on the woman ofc). With anal sex, somewhat different yung texture nung walls and somewhat warmer. Then the tightness feels concentrated where the actual hole is, like a cock ring.
Definitely an experience haha. But definitely scary for those on the receiving end. Kaya need ng madaming talks and co sent abt it syempre.
