Although you don’t think anything of it whenever you hang out with your male friends, a guy who is interested in you romantically is going to have an issue with it.
The truth is, the majority of the male friends you have would gladly sleep with you if you offered.
Regardless of how platonic you think the relationship is, a guy friend wouldn’t have to think too hard about sleeping with you if you offered it to him out of nowhere.
The way they look at each other as they walk into a movie theater together, walking hand in hand; walk through the hallway of a mall or shopping center; sit down to have a meal at a restaurant, etc.—it all looks like perfect bliss.
