When asking a woman out, I think you should tell her upfront if you want to go without a condom.

Maezawa here. This may sound a little cold, but if he refused to wear a condom, you should have left right then and there. Just get dressed and leave without doing anything. If he physically prevented you from leaving and forced you into it, that is rape. Even so, people may tell you things like, “But you went into the hotel together,” which can leave you feeling deeply frustrated. Even then, you should do everything you can to leave. If there’s no consent, the priority isn’t contraception—it’s not engaging in anything at all and leaving. If you have your phone, you can hold it and tell him, “If you go any further, I’m calling 110.” If he takes your phone, call the hotel front desk. In any case, if you feel uncomfortable, refuse as firmly as you can. The best thing is to leave. This isn’t a sex-work establishment, after all… And please report this to the club as well. If there’s no consent, this isn’t a situation where you should be saying, “At least use contraception.” The best thing is not to engage in anything at all and leave. It’s unfortunate that you’ve lost contact with him. I strongly encourage you to report this matter to the club.
