Honestly don't worry. In Islam, marriage is encouraged
a lot, and refusing to marry someone because of something that isn't really relevant (looks, money,
virginity) is a sin (i think). Prophet Muhammad's (pbuh) wife Khadija was not a virgin when he married her. In Islam it is also encouraged to marry divorced/widowed women and look after their children. It honestly doesn't mater, you just have to repent about losing your virginity before marriage, because you have sinned.
If your husband/boyfriend/fiance disrespects you or treats you badly because he wasn't the first one to take your virginity, he's not a good Muslim and is selfish. A good Muslim man would respect and love his wife, as she is a blessing.
I, personally, would tell my boyfriend that I'm not a virgin (I'm female) , if he really loves me, he probably won't care, because now he has me.
Tbh the only main concern my husband would have is whether or not I used protection, in case I got any STD's
So don't worry! A good person would respect you, no matter if you were a virgin or not!
