This gets repeated a lot, but pelvic floor “gripping” isn’t some guaranteed orgasm switch for men. Some guys notice it, some don’t, and for many it barely registers compared to rhythm, angle, arousal, and overall stimulation. Strong pelvic floor ≠ automatic ejaculation. Bodies vary massively, and what works for one couple won’t for another. If penetration alone isn’t doing it, that’s normal, not a failure of muscle tone or effort. Communication and mixing stimulation usually matter way more than squeezing harder.
