introductions :) 22 male rather healthy 75kg 175 cm rather built. have dabled in drugs no addiction just a few nights out havent gone near them in ages. apart from that i couldnt help but notice immediatly after ejaculation my heart rate was 43 the other day 45 so i did a test run earlier with some very exciting material in hopes of getting my heart rate up but still low 40 im highly sexually active with my partner id also boast awesome self controll but definetly a fast heart rate during sex easily 150 -160 if im smashing it. pardon my expressions just being truthful. so my question is why am i pumping 40-45 beats per minute during rigorious masterbation? i would assume fitness but 40 really i doubt it.
