well... what's a serious relationship... one that has you walking between opinions?... what is he going to think of me and all that? that sounds more like a serious prison...
I see no point in postponing something that you want just because someone may have an opinion about it. I strongly reccomend being your natural self, that may not get you all the people in the world, but it will keep around you those that love you as you are. Be it Passionate, spontanious, sexy or anything else.
If love is here to stay, for as long it may, be it one night or 20 years, celebrate it.
