Male here...in my younger years including dating my now wife, I could pull off 3 rounds with the right girl. I've done 4 in a long night.Depends on the bull. My husband has fucked me for 45 min and one bull for 10. Its all about the expierence and person. My husband in a MMF with a bull came 4 times in 2.5hrs. The bull came 2 times so my husband fucked me twice as much. Its about the person not the color. Now I’ve had a couple bulls who were multi cummers fuck me for 3 hrs straight cumming several times and I loved it.
Mid 50s now. It was once and done with some good oral mixed in before, during or after.
We're into mfm fun with a guy we know semi regularly. We always do her twice each, I've gone 3 many times, he's done 4. It just depends on how the night's going.
