I haven't really bought any sex toys as of yet, but hopefully I will do soon.
I can give a bit of heads up: I'm going to be buying this beaut. http://www.lovehoney.co.uk/product.cfm?p=13992
It doesn't contain nasty chemicals and I feel it's a good size for myself as I don't want to start with something small, but definately not too big, as I'm an anal newbie.
Strap-on is also my fantasy. Pegging's the word for it, but that word seems off-putting as it somewhat makes it seem like a comedic thing. :/
Are you looking strictly for Aneros toys or are you looking for what anal toy to buy in general? For myself, I'd rather have something which feels lifelike despite being straight.
