If I'm not a virgin, do I have to tell my husband before marriage?

So there are a number of things that we need to bear in mind here. Number one, we know the general prohibition in terms of exposing one's sins. But on the other hand, we know that one should always be open and honest, and in particular when it comes to a potential spouse. So how do we go about this? The way I would suggest it is, let's say you're looking for a potential spouse, and you're looking for somebody who has not had intimate relations with anyone else. You would say in the conversation, in an appropriate way, something like, the person I'm looking for is somebody who has not had intimate relations with anybody else. You don't need to tell me if you've had or not, but at the end of the conversation, if you feel that you haven't met any of the things that I've asked for, that I'm looking for, then just say you're not a suitable suitor for myself. That way, it's clear that you know what you're looking for, and the other person hasn't exposed any sins, but also you're both clear in terms of that it's not something that going forward would be suitable for either of you. So that's the way that you should do it. Don't expose your sins, but at the same time, don't hide it. If you are asked directly, and if you're asked directly, you could say, okay, look, let me answer the other questions you have first, and we can say at the end whether I meet all of your criteria. And then at the end, you could say, look, there are certain criteria I don't meet that you're looking for. Again, that way doesn't expose any of the things or any particular sin.
