Venus - I am not qualified to judge your reasons for wanting to have the sort of sex you want.
What I do have experience of is online fetishists.
I could write a guide to staying safe online, but really that's not relevant. You need to remember that you don't know this person. You also need to remember that if he's making you uncomfortable in cyber space, you don't need him in your RL space.
Anyone who (well, any man technically, but I also apply this to sexual assault by penetration) puts their dick where it isn't wanted is a rapist. That's the fact, that's how it is, and anyone who says otherwise is a dick and best avoided.
Anyone who is pushing your boundaries and not listening to your no is a dick and best avoided.
And anyone who is saying "no safewords" you should run like fuck as fast as you can in the opposite direction.
I am a Domme, a lifestyle Domme, it's who I am to the core of my being, I can't change it.
I am at the beginning stages of dating a new man. Our first date was to an all you can eat Chinese and we talked all night about life, work, family. Our next date is going to be grabbing a burger and going to a quiet pub. And we'll talk about life, work and family.
I appreciate it's different if you want to meet to partake in just a scene, but even then - get a different mobile so that you can bin it if he gets troublesome, don't give out your real name, don't share photos - all the usual keep yourself safe stuff. Tell someone where you are going and who you are meeting - I did that on Tuesday night I told a friend where we were going and who I was meeting (slightly different because we had met in RL at an event, but similar)
Don't partake in a scene with some random off the internet FGS. If you are that interested, go to a munch, (they're easy to find on the Black site) meet some real kinsters in the flesh (we are really just ordinary!) and take your time and take it slowly.
And remember - if it sounds too good to be true, it probably is.
