I forgot to receive my allowance

How should I bring it up? I had an overnight date with someone I’ve met several times, and of course we had an intimate relationship as well. I usually receive cash from his wallet at the end of the date. The date was so much fun that I felt really satisfied by the end, and I know it was also my fault for forgetting, but… I didn’t realize until I got home that I had forgotten to receive my allowance. We already have plans for our next date, so I’d like to receive it then. How should I bring it up without offending him and still make sure I receive my allowance? I sent him a message thanking him for the date, hoping he might bring it up himself, but he didn’t mention the allowance at all. Something similar happened with someone I used to date several times. During trips like that, he either reduced the amount or didn’t give me an allowance at all. At the time, I wondered if it was because he had more expenses than usual on the trip, but I felt uncomfortable bringing it up. After that, the reduced payments—or no payment at all—continued, so we eventually ended things. It makes me extremely distrustful and wonder if he’s hoping to have an intimate relationship for less, or even for free, if he can get away with it… He’s a very kind and wonderful person, and I’d like to continue this relationship, but honestly, receiving an allowance is an essential part of it for me. I’d really appreciate advice from both women and men. Thank you.
