Despite differences in height, weight and other physical characteristics, the location of the prostate gland – 2 to 3 inches inside the anus – is the same in approximately 98% of all men. With an insertion length of approximately four inches, our Aneros massagers compensate for differences in physical dimensions.
That said, different Aneros models have different girths. With exception of the Eupho, all of the larger size models are intended for men who are more experienced with anal play. If you’re interested in some general guidelines for a model that might a good fit for you, check out the Choosing a Model page. Ultimately, this is a personal decision. People of all sizes and shapes from all over the world own different models, even multiple models, and preferences vary.
