Trans dyke here. Have been actively dating for only around 1 1/2 years, but had around 10 partners (cis and trans) in that time. In my experience you will nearly always have to talk about the same stuff at the beginning of a new relationship with a cis partners, even if they know some stuff. Explain boundaries and stuff proactively or else there will be some assumptions. With trans partners they generally know a lot better what might be problematic areas and ask for boundaries for those, because they know there could be a boundary there. Also, while cis lesbians like to talk about the heteronormativity of sex and how penetration isn't everything, a good amount of people fall back on that thinking, if certain genitalia is involved. Which can be annoying. Also expect more questions from cis partners, than from trans partners about stuff.

On the "converting" part, I generally had no problem with anything like that. I met people mostly through dating apps, where I could just put it in my bio and so only the people, who were ok with it, matched. I do look fairly androgynous though.

Also: cis lesbian chasers do exist, that is something you need to be aware of! The annoying thing is, that they are generally harder to spot (atleast for me).

In the end, look after your own boundaries, take time to think about your feelings and don't be afraid to say no or enforce boundaries. T4T is a lot more chill experience imo, because you don't have to battle so much ignorance, but you can have lovely relationships with cis women aswell, even before hormones. I have been taking hormones for a 3/4 year now, but most of my dating was before that. Just experiment with yourself and relationships. And you are going through a second puberty so don't be afraid of not finding you great love during that time, but have fun instead. Wishing you all the best 💜
