There is some wisdom in the posts above, the truth is it's the way things are online.
My advice here is not directed at you alone, its meant to be general for anyone Dom or sub wanting to know how to find lasting relationships online.
People can hide behind their nick never revealing anything much about themselves, it seems real and it is, you become invested in the relationship and so get hurt in just the same way as "real life".
You have no way of knowing, especially from the first few messages what someone is really like and this is where the main issue occurs. Too many people are in a hurry, they want to find their Dom or sub NOW. It doesn't work like that, spend time chatting and if after a few weeks they are still interested in you and you in them, you can begin to commit a little more.
There are many who seem to treat online partners like characters in a video game, you can "shoot 'em dead many times but they always come back" seems to be their attitude. I have seen some really stupid and often really dangerous suggestions offered by supposed Dom's as tasks for their online subs, things that in person they would never attempt or suggest. To these types, just dropping out and breaking your heart is nothing.
On the flip side there are submissive types that are really just fantasy collectors, too lazy to find stories themselves they want creative Dom's to feed them. Typically for this persona a Dom may write a long and detailed task only to receive a one line response asking for more.
So my tips for spotting someone worth cultivating as potential partner;
1. Do you get back equal or similar amounts to what you give them? If you seem to be the one doing all the work just in messaging it isn't a good sign.
2. Work out time zone differences. This can be more problematic than many realise, if you want to proceed make sure you both understand what the cross over times are.
3. Don't let yourself be bullied into doing something you don't like, D/s relationships are built on trust and respect just like any other. Take the time to work on finding your common ground, the kink world is big and there are many kinks, often you will find you don't share many common kinks and this will lead to you wanting to seek them somewhere else.
4. Don't commit to anything for at least a couple of weeks. Now I know this may sound outrageously long to some but it's not, as staff here I know how quickly some people come and go, there are almost 40000 registered here and less than 1000 active. Your dream Dom or sub may be long gone in 10 days.
5. Be realistic in your expectations. Online Doms cannot give full time attention and online subs cannot serve full time. We sleep, eat, go to work or school and have a myriad of other daily commitments, this little corner of online kink is for many just a distraction.
6. DON'T PANIC if you can't find a match for you in a week or even a month, it doesn't mean there is anything wrong with you. It is well worth taking the time.
7. Rather than posting ads try messaging people you find interesting direct, read the profile and posts by that person and when you do message make it interesting, not "kik me xxxxxxx". If the person doesn't have any info in their profile or has only posted scant one sentence posts be wary, they are most likely going to be lazy in other respects.
I hope this helps some of you to find some more lasting relationships.
