Sex can be a part of love and love can be a part of sex, but one does not automatically equal the other. Thinking that having sex with someone will make them love you is not a reality. And someone telling you, “If you love me, you’ll have sex with me” is pure manipulation on their part.
If love is something you require before you have sex, then own it. There is not a problem with that. You owe it to yourself to make 100% sure it’s the real deal before you make that decision.
This is your life, not anyone else’s. Make the right choices for you.
