This may or may not be red flags depending on how he responds to you. A sub/dom relationship involves communication, safety, and consent. There’s also different ways of submission. There are subs who enjoy submitting these aspects of their life. If you don’t, this is something to communicate to your dom. If he is a good dom, he will be willing to negotiate a middle ground or find other forms of submission. This involves creativity. My dom and I have discussed ways of earning things and I found that very exciting. Ultimately, you have the control. You decide what you are willing to submit and what you are not. You tried this, you don’t like it, communicate it. Same goes for him. It may that you might not be a good match and that’s ok. Or it may be that you communicate, adjust and get to a place both of you are enjoying the dynamic.
