Adult baby/diaper lovers (AB/DLs) enjoy role-playing as babies and/or wearing diapers. They also engage in other related activities, such as urinating or defecating themselves and having an adult care for them. Previous surveys have revealed that AB/DLs commonly report sexual motivation, a finding that is corroborated by case reports in the psychiatric literature and some media interviews. The fact that AB/DLs change their appearance and behavior to become more like babies raises the possibility that they have an erotic target identity inversion (ETII). In ETIIs, a person’s external erotic target is inverted into the self, resulting in sexual arousal by the fantasy of being a member of the target class or by imitating one. If AB/DLs are sexually motivated by an ETII, they should experience both sexual attraction to babies and sexual arousal by the fantasy of being a baby. We surveyed 207 male AB/DLs recruited from the Internet about their sexual orientation, sexual motivation, and sexual interests for a primarily quantitative analysis. Consistent with past research, a substantial minority of participants reported non-heterosexual identities (42%), and a large majority reported some degree of sexual motivation for being AB/DLs (93%). Wearing diapers and urinating or defecating oneself were rated as especially sexual. Even though 40% of participants reported sexual arousal by the fantasy of being a baby, only 4% reported sexual attraction to babies. This pattern of results is contrary to predictions from the concept of ETIIs. Instead, participants indicated that physical or mental pain, humiliation, and an adult woman were important to their sexual fantasies of being a baby. Masochism appears to be a promising alternative to an ETII for explaining the sexual motivation of AB/DLs.

成年婴儿/尿布爱好者 (AB/DL) 喜欢扮演婴儿和/或穿着尿布。他们还从事其他相关活动，例如自己排尿或排便以及由成人照顾。之前的调查显示，AB/DL 普遍存在性动机，精神病学文献中的病例报告和一些媒体采访也证实了这一发现。AB/DL 改变了他们的外表和行为，变得更像婴儿，这一事实增加了他们患有色情目标身份倒置（ETII）的可能性。在 ETII 中，一个人的外在性欲目标被倒置为自我，通过幻想成为目标阶级的一员或通过模仿目标阶级的成员而产生性唤起。如果 AB/DL 受到 ETII 的性动机，他们应该体验到婴儿的性吸引力和幻想成为婴儿的性唤起。我们对从互联网上招募的207名男性AB/DL进行了调查，了解他们的性取向、性动机和性兴趣，进行初步定量分析。与过去的研究一致，相当少数的参与者报告了非异性恋身份（42%），而大多数参与者报告了 AB/DL 具有某种程度的性动机（93%）。穿尿布和自己排尿或排便被认为是特别具有性行为的行为。尽管 40% 的参与者表示因幻想成为婴儿而产生性唤起，但只有 4% 的参与者表示对婴儿有性吸引力。这种结果模式与 ETII 概念的预测相反。相反，参与者表示，身体或精神上的痛苦、羞辱和成年女性对他们作为婴儿的性幻想很重要。受虐狂似乎是解释 AB/DL 性动机的 ETII 的一个有前途的替代方案。
