This is some advice, to be taken with a grain of salt of course because all dommes are looking for different things.

If you're a sub who is 'inexperienced' and having trouble finding a domme or connecting with dominant woman, it is likely because of how you present. Approaching a d-type and giving them a title, trying to engage in a dynamic right away or sayings things like "I have no limits" are instant red flags.

When I'm approached by a sub with the characteristics I will list below, I view them as 'high value' subs and am much more interested in potentially pursuing a dynamic with them. It still might not be the right fit, but you'll definitely be noticed amongst the sea of subs simply looking for a kink dispenser.

Engage with purpose and humility - WHY are you choosing this specific domme? When you approach without having a reason OR knowing nothing about them, it immediately shows that you don't care about whom you submit to. If you don't value your submission, it has no value to anyone else either. Be respectful, intentional and don't make assumptions.

Show your 'worth' by how you value yourself - The intangibles that make a sub 'high value' are what make you stand out! This list could get exhaustive but just some examples: you're emotinally intelligent, you prioritize your mental health, you have goals that you're actively pursuing (could be anything from getting a raise to learning how to cook or surf), you exercise or meditate, you take time for self care, you limit your porn, etc... All meaning to say that you have spent the time to do the self work to be a good partner.

Complete steps of self exploration/training - Let's say your goal is to run a marathon. You won't know what that will be like, but you can begin practice runs and training to prepare you. The same goes for being submissive... practice some of your interests on yourself. Learn some ropes skills if you're into bondage (might come in handy to help your domme tie you up!), begin anal training if you hope to engage in pegging (learn proper cleaning and hygene), go online and learn slave positions, read articles on how to be great at begging (it's truly an art--- there's so much more to say than "please") and the list goes on. You can lack practical experience, but having knowledge will be incredibly helpful. There's nothing more EXHAUSTING than being approached by a sub and them saying, "I don't know what I like, but I know I'm submissive." It just adds more work for your domme that can feel daunting.

Respect yourself and your domme - Maybe your kink is degradation and humiliation. That doesn't mean that's what you should seek right out the gate. Seek to be degraded, respectfully, after you've both consented to engaging in that kink. Parameters have been negotiated and limits set. Not to mention it's such a turn off when an initial message is "Treat me like slut."

Ask yourself, are you approaching a domme because YOU want to serve her or because you want her to serve your submissive kinks - A good way to check yourself on this is asking, how much of what you desire revolves around you RECEIVING vs. you GIVING. Being a dominant, there is an implied acceptance of labor. The dominant is responsible for actions, so you might think it's normal for you to say, "I enjoy being tied up and edged," which is awesome (who doesnt? haha) but then as you continue, the list sounds like this: I want to be gagged/pegged, I want humiliating tasks, I want to feel used, I want to be punished.... suddenly, this is starting to become very unnapealing because of the labor involved. Prioritize what you're giving to your domme first and allow her to decide in which ways she will allow you to receive.

Participate and contribute to scenes - Ask how you can help. Maybe you can clean and sanitize toys, set up equipment, help her get ready, suggest some options to help ease her into domme space (you seem tired, can I offer you a massage... I will get into this position because it will be easier for you to xyz...) I know it seems enticing to say, "I'll do whatever you want," but instead you can make suggestions on directions a session can go. As suggested in the comments, you can take lessons of all types (improv, dancing, etc) to make role play more fun and engaging.

Appreciate your domme, her time/effort, labor - You might be the one with the praise kink, but most likely she will love to hear how you've noticed everything she's contributed. Think about the money she spent on her nails, outfit, the time she's taken to get ready/choose outfit, prepare the scene and make sure she feels seen as a person. I can tell you from experience that it is expensive to be a domme. Nail, hair, outfit, grooming like waxing, etc can easily run up to a couple hundred dollars a month. Don't take anything for granted.

Know your domme is a person too - They'll have days where they might not be able to get into the right headspace. Have compassion for them.

Consider consent and safety - You have limits, boundaries and proper protocols set up to ensure sessions don't go too far. Take a moment to read up on how to negotiate and also discuss aftercare prior to a scene. A sub who knows how to take responsibility for himself is showing how he values his submission.
