I am interested in getting my first toy, but all I have experience with are plugs. Where should I start? I was thinking Roland, but I read that maybe the point isn't great so maybe start with Austin. How true is that? Should I get a cum tube for continually lubrication? What firmness is best for beginner anal play? How important is the knot? I read that some people can't orgasm without the knot, again how true is that? Any and all help or advice would be genuinely helpful, thanks in advance.
