I have been bonking regularly for about 30 years and I am still going strong; at least once a week but very often two times a weeks coz sex can be very addictive.
From my experience, with foreplay and intercourse, the best is about 25-30 mins. Most women will loose their urge once they achieve orgasm; sometimes they can have two or three in a session. After that they dry up and if with condom can be uncomfortable for them.I often ejaculate after 8 - 10 mins and feel good after that. Too long and I will be tired and body also ache.
