Sex is necessary to maintain a proper marriage situation. Yes. But when it comes to having sex when you are not married, then no, since getting to know a person must be first from his character, how he overcomes difficulties, how he loves other friends, how he treats money, animals, things . . . and all these have nothing to do with sex. And once you decide he is the greatest friend in your life, and he agrees to the same, then get married, and enjoy what God has given you in a proper situation.
