Your boyfriend likely enjoys skin-to-skin contact for a combination of physical and emotional reasons.
Physical Reasons:
- Sensory Pleasure: The warmth and texture of another person's skin can be inherently pleasurable. As noted in a Quora response, the simple warmth of another's touch can be psychologically stimulating and exciting.

Emotional Reasons:
-
Oxytocin Release: Skin-to-skin contact triggers the release of oxytocin, often called the "love hormone." Oxytocin fosters feelings of bonding, trust, relaxation, and intimacy. It also helps reduce stress and anxiety. ([Oxytocin: The Love Hormone](Reference Source))

Comfort and Security: For some, skin-to-skin contact provides a sense of comfort, security, and emotional reassurance. A blog post about skin-to-skin contact highlights its ability to create feelings of comfort and security. (https://rosieweldon.com/sleepingcontact/)
