I don’t know how to console my sister

In the past she went through a bit of a wild girl phase and had sex with six guys in college and when she first moved to Tennessee. Eventually she came into Christianity and now regrets her behavior and feels like used goods. Now that’s she is religious she is worried she will never find a man who will love her. I told her there is nothing she can do about the past and though having sex was not advisable especially with six men someone will love her and look past her sexual history. She calls herself a whore. I was surprised she slept with six people and shocked yes but no one in her family is calling her a whore though. Some of her friends and acquaintances were worse. One had 10 partners and another had 17. These are young women in their early to mid 20s. Now my sister since getting raped ( by a guy she was dating) is fucked up and feels really dirty even when getting professional massages to help the discomfort/pain in her body. We all make mistakes and she wishes she could take back the drinking and trying cigars and recreational drug use like marijuana in her college years. She went wild. But now she grew up more and is going to be 24. I just wish she didn’t feel so terrible about herself. She found god and it changed her perspective on her self worth and made her respect herself more in her behavior. Now she wants to wait until marriage before having sex again. Getting raped she said woke her up in a way. Traditionally Romani girls and women are supposed to remain virgins until heterosexual marriage. My sister and I are half white half Romani. I feel for her. She also got molested by another kid as a child so I don’t know if during college that made her act out. I thought she slept with three men total not six. So yeah it makes me feel pity for her. I just hope she stops beating herself up for the foolish decisions she made when young and dumb.
