Apologies if this has been asked before, but a search of the forum didn't come up with anything. And also apologies if this is a sensitive topic and one people prefer not discussed.
Essentially my girlfriend is pretty into anal and we probably do it more often than vaginal. I'm not huge in size, but bigger than average, and can go quite hard for reasonable amounts of time. With all that said, and with her genuinely enjoying and well experienced, the longest we've ever gone pretty hard for is like 10 minutes. She cannot understand how the girls in scenes like those on legalporno can do it so relentlessly with huge dicks for an hour or more. There's plenty of scenes with just a guy and a girl, but the anal pounding is extraordinary.
Are there tricks to it? Perhaps some sort of local anaesthetic gel?
She/we wondered if drugs might be involved. I'm no expert at all, having lived a very sheltered life where drugs are concerned, but the girls don't seem to be high or out of it in any way. Doing some reading though and perhaps ketamine is involved? I believe it's quite useful and enjoyable for the receptive anal partner and in lower doses wouldn't necessarily have too many outward effects. Or perhaps alcohol? Although again the girls don't seem drunk or even tipsy.
Or are they just that next level of anal heroes? haha and can just take it. The likes of Kristy Black, Nela Decker, Sara Bell, etc.
We/she may even be keen to try something like that as she'd love to go longer...as would I

No dispersions here either. Cool if people are doing it. And apologies again if nota. topic for discussion.
