About This File
I think you've seen this forum with the unfinished HDT mod for the anus https://www.loverslab.com/topic/94423-hdt-anus-physics-update-pesmp/page/18/. The author of the topic uploaded hdt xml files a couple of times, but many could not find a use for it when the author left. All I did was rename hdtVagina&ButtHole to hdtVagina and replace the original file in SKSE/plugins. The physics for the anus and vagina worked, but were quite buggy and did not react much to collisions, so using the Just for fun program and editing the XML files helped fix the problem, but everything is still not perfect. I used BHUNP body. To support creatures, use Animated beast cocks.
P.S. I'm a complete zero in modding, so I won't be able to improve this config. If you're good at it, then please do whatever you want.
To install, simply replace your hdtVagina in the SKSE/plugins folder with my file, do not forget to make a backup
