Dear stillvirgin, of course it's possible! I don't want to bore you or anyone else here so I try to make it short and sweet!
First thing first, everyone here understands you and they are not trying to make a joke out of this. Trust me. Each and every reply here is to share something with you. Just read them over and over and you'll know what I mean.
There is nothing wrong with falling in love with a MP. After all, what is the difference between an MP or the lady who works as an executive in a big company? They are both human and both have feelings. In fact, I know a few of them who actually quit their jobs and married their clients and so far so good ...
However, remember that any kind of relationship should be like a 2 way street. Don't waste your time, otherwise.
Take care and enjoy life ... it's so short!
