Kia Ora Paige,
I think somebody else had mentioned it, that what attracts people to other people varies...One has only got to look at the cis world of opposite and same sex couples... There are 'paired' beauty and the beast, beauty on beauty, beast on beast, one can 'never' say never when it comes to who will be attracted to whom...There's physical attraction being the most common, but then there's other types of things that draws people together romantically other than their physical appearance....
For me personally, I have no desire for an intimate relationship, I blend in quite well and have the odd admirer or three, but I'm what you would call an asexual bi-affectionate/romantic with no desire for any kind of intimate relationship...I'm totally 'content' with my current status quo...
So I guess in answer to your question, I would have to say YES my level of happiness wouldn't change if there were no romantic advances towards me...
After all, in a past life I had "been there and done that and have got the memories to prove it !"...
