Soloanalist

im a middle aged guy that has been pleasuring my anus for many of years with all kinds of toys and dildos so i don't concider myself a beginner. Lately i have been wanting to take my solo anal pleasure a bit farther by taking long dildos deeper than i have before. I have pretty much had a stopping point inside of me that would not let anything go deeper. I have been reading up on this topic trying to educate myself on deep anal penetration. Im not looking to stretch out my anus or make a rosebud im just wanting to have average thickness go in a lot deeper so any and all information on this is greatly appreciated. Not only by me but my hungry butt as well. I know the basics of this already like patience, lube lube and more lube, slow insertions, pushing out while being penetrated and the use of slinks and other tapered toys. My budget is limited and these expensive toys are something i would love to have but can't.
