Next time you have a new partner who isn't great in #bed and you feel like telling them, "Do I need to draw you a map to 'where the #erogenous zones are?" - know that someone has already done it, and you can give them that instead.

There is also a newer one from Stelmar et al., which seems to be more details - but none of my institutes appear to get me past the paywall.

Topography of Human Erogenous Zones - Archives of Sexual Behavior
Touching is a powerful means for eliciting sexual arousal. Here, we establish the topographical organization of bodily regions triggering sexual arousal in humans. A total of 704 participants were shown images of same and opposite sex bodies and asked to color the bodily regions whose touching they or members of the opposite sex would experience as sexually arousing while masturbating or having sex with a partner. Resulting erogenous zone maps (EZMs) revealed that the whole body was sensitive to sexual touching, with erogenous hotspots consisting of genitals, breasts, and anus. The EZM area was larger while having sex with a partner versus while masturbating, and was also dependent on sexual desire and heterosexual and homosexual interest levels. We conclude that tactile stimulation of practically all bodily regions may trigger sexual arousal. Extension of the erogenous zones while having sex with a partner may reflect the role of touching in maintenance of reproductive pair bonds.
