If it is too fast this means one party is not agreeing with the advances and it will therefore lead to conflict.
If you are meaning fast compared to other couples then you might be alright as long as the partner agrees to the set speed2

You get too attached too quickly , without really knowing that person. Then it's like a shock to your system when you find out they aren't the person you thought they were. Once you're attached to someone its not so easy to let go. So you end up staying in a relationship you're unhappy in... for far longer than you should0
