It sounds like you're describing a particular physical gesture or approach to intimacy that you've observed can have a certain effect on some men. Sexual responses can vary significantly from person to person, and what works for one individual may not necessarily have the same effect on another.
Physical gestures, including those involving touch and intimacy, can be powerful in eliciting various reactions, but it's important to approach any physical interaction with respect and communication. Consent and mutual understanding of boundaries are crucial in any intimate situation.
If you are engaging in intimate activities with a partner, it's important to communicate openly about desires, preferences, and comfort levels. What works well for one person may not be suitable for another, and everyone has different preferences when it comes to physical intimacy.
Remember that sexual experiences should be consensual, respectful, and enjoyable for all parties involved. It's always a good idea to prioritize communication, check in with your partner, and ensure that you both feel comfortable and respected in any intimate interaction. If you have specific concerns or questions, discussing them openly and honestly with your partner can contribute to a healthy and mutually satisfying intimate relationship.
