So, we have decided to try something new, and she wants a strapon to try on me, but I insist she should also have pleasure, we are about to order: http://www.lovehoney.co.uk/product.cfm?p=809 and was wondering if there is a dildo that will also do it for her and not only for me.
The kit that you're going to order does come with 2 different size O rings so just check the size of any other dildo you want to purchase and make sure its compatible. Live chat will be able to help, if you're not sure.
Can second the idea of a 'strapless' type. However, in our experience they all need a harness to make them work well. A harness holds the saddle of the toy against the clit and generally stabilises it so you can thrust properly. The Share mentioned above is good and the Share XL, the slightly bigger version with ridges, is our all time favourite.
Expect to try a few before you fine the one that is perfect for both of you.
We would advise on using a harness but, with a bit of practice (which is part of the fun anyway) you may not need one. Fantastic feeling for both and a very worthwhile purchase.
