I’m a Type C.

I’ve never used a menstrual disc myself, so I’m not familiar with the actual experience or finer details of using one. I hope you understand. That said, from your question, it seems that what you’re concerned about isn’t so much whether it’s possible, but rather being considerate toward your partner. Considering that you’re a C-type woman and this is your first date, I don’t think there’s any need to bring up your period right from the start. It would probably feel most natural to focus first on the first meeting and dinner, then mention it once the man is clearly interested and the mood becomes more like, “So, what should we do after this?” Even then, I think a light, uncomplicated way of putting it would be enough. For example: “Actually, my period started unexpectedly today, and I’m using a menstrual disc. Would that still be okay with you?” I feel it would be best to leave the choice up to him. Just adding, “If you’re still okay with that,” can give him the reassurance that he doesn’t have to go any further if he’s uncomfortable. Your concern about menstrual blood or the feeling of a foreign object is very understandable and important. Some men are uncomfortable with blood, and there is always a possibility that he could be surprised if he touches it without knowing. In that sense, letting him know beforehand is not necessarily a negative thing at all. If he seems hesitant or reacts as though it might be difficult, that isn’t your fault, and since this is your first meeting, there’s no need to force yourself. Taking things carefully as a C-type woman may actually leave a favorable impression. Rather than trying to hide it, I think the best approach is to choose the right moment, explain honestly, and leave the decision to him by saying, “If you’re still okay with that.” That kind of distance feels just right for a first date. Even though something unexpected happened, I think it’s wonderful that you’re being so considerate of the other person. Please don’t push yourself, and prioritize the choice that makes you feel comfortable and safe. **Update:** After reading the other respondent Paper Airplane’s opinion, I realized they were absolutely right. If you already know about the situation beforehand, I think the most considerate and reassuring approach would be to consult the club before meeting and consider adjusting or postponing the date. My answer ended up assuming a last-minute situation where the day had already arrived and you were forced to make a decision. I apologize. If you’re considering continuing things with this person, I also agree that it’s especially important to proceed carefully on the first meeting. If possible, arranging things through the club would probably be the least stressful option for both of you.

I looked it up online. Periods can’t be helped, so I think it would be best to reschedule. The questioner should take the initiative and suggest some alternative dates. That said, hindsight is 20/20. Even if your cycle is irregular, you can usually get a rough idea of when your period might come. If it hasn’t started by the expected date, you can let them know in advance, or try to avoid potentially risky days as much as possible. I think that’s the key to making the arrangement work smoothly.

“Menstrual disc?” I searched it, and apparently it’s something that only came out fairly recently. That said, I clearly hadn’t done my homework. Anyway, getting to the point: You say, “I unexpectedly got my period that day,” in the past tense, but then say, “I’m thinking of wearing a menstrual disc and going on the date,” so I’m not quite sure I understand. With a first date arranged through Universe Club, the plan is to start with a meal. If you were going to mention it, I suppose the time would be when he invites you to a hotel after dinner. That said, it might also be fine to go to the hotel without saying anything, see how things unfold, and if he doesn’t say anything, just leave it at that. The question is how much discomfort the man would actually feel. If it would be very noticeable, you might feel that he should be told in advance. But since I’ve never heard of anyone complaining about this before—perhaps not many people use them yet—it’s difficult to judge. P.S. Apparently, menstrual discs come in disposable and reusable types. Looking at photos of the disposable ones, they seem thin, almost like condoms, while the reusable ones are made of medical-grade silicone and appear to be slightly thicker. The reusable type also says: “When you use the auto-dump function, the menstrual blood is released, so your hands don’t get dirty.” It also says that “auto-dumping is easy if you simply bear down,” so it sounds convenient. However, I imagine you might bear down during sex. If that happens, the disc could auto-dump during sex, causing menstrual blood to come out anyway and defeating the purpose—possibly staining the sheets.

I think it would be best to let the club know and discuss it with them before meeting him—even if it’s right beforehand. If you wait until you meet him that day, he may take it as you turning him down or not being interested, regardless of when you bring it up. By informing the club, you may be able to cancel or postpone the arrangement. Letting them know about your physical condition (your period) is a perfectly valid reason, so there’s nothing strange about it. If you’re considering an ongoing arrangement, I think it’s important to take the first meeting seriously and proceed carefully. If you tell the club in advance, the man may decide that, since you’re a Type C, he would or wouldn’t want to meet even if you’re on your period and there’s no adult relationship (intimacy). He may cancel rather than meet under uncertain circumstances, but you’ll still be able to arrange another meeting properly. Especially if it’s right before the meeting, I think it’s best to inform the club. If you meet after he knows the situation, things may turn out differently.
