Thank you for all your responses, there are too many to reply to everything. Vicarinatutu, gamerwidow, sardinequeen,compochel, clothesofsand, and several others, your contributions have been very helpful.
To the poster who asked if this was a religeous decision ( sorry, I can't find your post to get your name now) No, it is a sexual orientation. As far as I know, I was born like this, I don't feel sexual desire. Thank you for taking an interest and asking . Another poster said it must be like if you are a straight woman, and never feel any attraction to another woman, except you feel like that to men too, yes, I think that sums it up, exactly, for me.
Yes, to the poster who asked, I can feel romantic attraction, however, I wouldn't bother to have even a romantic relationship, too time consuming, and I have very little motivation.
I think after reading all these responses, I have decided to buy my ring. I think it might be a good idea if only to increase awarness. I'm not young, but it would be nice to think I had contributed to greater understanding and acceptance for those asexuals who are young now, and in the future. It can feek very odd, if every book/film/song tells you you are the only one in the world. actually there are millions of us!
No, I haven't lost a huge number of tfriends through misunderstandings, but good friends are not something to lose easily. Also, the ring, and any conversations it triggers, may prevent the other , actually more common problem, married or single work colleagues ( male!) who think "I'm just making mysekf a cup of tea, would you like one" is some sort of secret flirt code. It would be nice just to be my normal friendly self, without worrying about being misread.
I like phantomPaynes idea of a black ring on the ring finger instead, that mightbe a tgood idea. I'll have to think about that.
