My sexlab installation feels incomplete

[Nickolkiin]

what I mean is that for starters most immersion is broken from penis clipping through my actors during intercourse. I'm familiar with a penis shortening mod to help with this but I feel that there is more out there then this that I haven't come across. second vagina and anal opening isn't happening in my game how do I insure that it does? I am unfamiliar with setting up the cbpc and smp physics for collision during sex, is there a walk through that's on LL?
