When it comes to sexuality, every individual is unique, and what may be sensitive for one person may not be the same for another. However, here are some commonly sensitive areas on a man's body:

1. Genitals: The penis, testicles, and perineum (the area between the genitals and anus) are obvious erogenous zones.
2. Neck and Throat: Gentle touching, kissing, or licking can be pleasurable.
3. Ears: Softly touching, licking, or whispering in a man’s ear can be arousing.
4. Nipples: Some men enjoy nipple stimulation, whether it’s licking, touching, or gentle biting.
5. Lower Back: The area just above the buttocks can be sensitive and responsive to touch.
6. Inner Thighs: Gentle stroking or teasing can create a pleasurable sensation.
7. Buttocks: Some men enjoy spanking, touching, or licking.
8. Lips and Mouth: Kissing, tongue exploration, and oral sex can be intensely pleasurable.
9. Scalp: Gentle hair touching or scalp massage can be sensual.
10. Hands and Fingers: Softly touching or licking fingers and palms can create a sensual experience.

Remember, everyone’s preferences and boundaries are different. Communication and consent are essential for exploring and understanding what works best for each individual. Prioritize mutual respect, trust, and open dialogue to create a comfortable and enjoyable experience. If you have specific questions or concerns, feel free to ask!
