Intimate and romantic images of people not merely "having sex", but who are expressing love for each other in a physical way. Kissing, hugging, eye contact, hand-holding, and the like, rather than genital close-ups and spattered bodily fluids. Images that make hearts race and pupils dilate, and arouse the emotions as well as the body.
The equivalent tag on Pixiv is ๆใฎใใใปใใฏใน, "sex with love".
