>>508630128Do you have friends? When you spend time with people, with anything, you start to understand that person or even thing more the more time you spend with them/it. Thats lime life 101.
If someone is having sex with you is understood they are making themselves vulnerable with you, that is they are exposing/sharing to you more of them than they share with other people. And they like you and want you to understand them and help you out in understanding them because people like to be understood.
