Psychologically, by alleviating "performance anxiety" and rebuilding "body awareness," torso sex dolls offer a valuable practice environment for some patients whose ED is primarily psychological in origin. Physiologically, they provide physical feedback that is more realistic than manual stimulation, potentially helping to elicit and sustain erectile responses. 

It is worth noting, however, that while silicone demands a higher initial investment, its extended lifespan and lower maintenance requirements mean that—when amortized over the long term—it may prove to be a highly cost-effective choice. TPE's primary advantage lies in its budget-friendly nature, making it an excellent option for those looking to simply "try out" the experience or for hentai sex doll users who do not anticipate frequent usage. 

Academic research provides a deeper perspective for understanding the emergence of the trans sex doll. A study published in the *Journal of Sexual Medicine* on the use of torso sex dolls by transgender and non-binary individuals revealed a key finding: for transgender and non-binary individuals, torso sex dolls have a unique meaning beyond pleasure—they help alleviate body anxiety, release inhibitions, and affirm gender identity.
