It reminds me of an earlier post about a Dom (alledged) demanding the same in Scotland.
Get to know this person first, when, if the moment is right, you won't have any doubts. That you ask here means you are not yet ready.

That's a very poor view of a Dom.
Sure, there are 'players' who do act this way and subs who fall for it. But I don't believe a genuine Dom would behave like this.
A D/s relationship should be one of mutual agreements, consensual, respectful, and understanding of each partners needs, to be served, Read more… and to serve.
It could also be argued that a Dom 'serves' their sub and that a sub is always in control.

Firstly, you are an attractive young lady. Thank you for posting your photos, especially those taken in what would seem to be a professional photo shoot.
From these photos, very hot by the way, perhaps ask some deeper questions of yourself. For example, are you dressing as 'you' for you, or are you Read more… dressing to attract what may be the wrong person who wants what they see, but which is not really you?
Life is a difficult path to tread at the best of times, and whilst it is easier to grow by repeating positive experiences, it is also possible to grow by not repeating negative experiences.
Take your time, think carefully, and always remain safe within your own limits.
You are young and vibrant. Let’s have less if the little time life, take each day as it comes, and you will have many I am sure.
"The thought of not doing the things that I haven't experienced and so desperately want to, makes me sad."
Focus on this. It is you! Someone out there is desperately wanting to receive what you have to offer!
