Advice for a trans girl in her first relationship and how to transition from normal s*x to kink safely?

I need some sexual/relationship advice. Wanting to turn current relationship kinky down the road...

I (24 bi trans F, pre-transition) have been friends with this woman (23 pan F) for months now but she asked me out for Valentines day. I've never been in a relationship before, she has. While I'm not technically a virgin, she has more sexual experience than I do. I really like her and clearly the feelings are mutual.

While we were still platonic friends, we've talked about s*x before. She likes to be more dominant, and I like to be more submissive. I've never had s*x with a woman before and when I jerk off I usually do it dry into potty paper so I didn't know what a real kitty would be like. Plus, being a trans woman, I have a complicated relationship with my peepee to begin with. I've told her all of this so she knew this going in.

On Valentine's day, we had s*x at her place. She initiated it and the foreplay was FANTASTIC. She tried riding me and I didn't last long at all (even with a condom on). She then pegged me (something I've suggested in the past) and it took me a while to work up to her dildo and she went fairly slow. She pegged me for a while before jerking me off to completion, then had me go down on her. Despite being my first time giving a cis girl head, she told me she came twice.

Yesterday we talked about it and she wants me to start wearing a butt plug throughout the day, even at work. This way it can make my anus looser and all she needs to do is remove the butt plug, lube me up, then go to town. She also says the more she pegs me the easier it will get. How safe is this though? How safe is it to wear a butt plug all day long? And how safe is it to have anal all the time? I'm worried about the health of my rectum if we do this too often.

She did make it clear she wants me to give her head a lot. Besides pegging and cunnilingus, is there any other sexual activity y'all would suggest we try in the beginning? I really like her and I don't want her to leave because I'm bad in bed. I'm just looking for more ideas and options to explore. If it involves my peepee I'm willing to try most things at least once.

If this works out, I do want to try and introduce kink down the road. Neither of us have done kink before but I've always fantasized about it. Eventually I would like her to tie me up and experiment with S&M. I kinda also wanna try free use/CNC where she can physically overpower me and use my body as she pleases but I'm not sure how we could incorporate that yet. I've always fantasized about being submissive to a potential partner and now I'm loving the idea of submitting to her sexually.

Any advice for how to move forwards? I really want this to work out cause she's amazing and I'm worried my inexperience will ruin things for me.

You can start going to kink classes and demos in your local community. That is going to be the best possible resource for learning how to do kinky stuff safely and in a way you both enjoy.
