humm... I would simply say luxury for vibrators as you said you prefer rechargeable.
For me... ok... this might be easier... I'll group and link you. But just so you know, these are my preferences and most of them are a pretty penny.
Pure Wand: link
Sapphire Falls link
(in my opinion, the most powerful vibrator on the market today)
Anal: Bootsy: link
For g-spot dildos, I find a bigger, bulbous head to be the best idea as then there is no need to search for my g-spot. I can apply as much pressure while sliding the toy over it as I need. Not to mention, that usually with the other end, it is smaller, and a partner can hold on to bigger end and use the smaller end on me anally. But not wise to use on your own as you might let go and it will vanish!
For g-spot toys, I like a similar design with the curve. I've yet to find the "perfect" g-spot vibrator as I want a uber powerful motor with a very stiff neck. I have the vr6 which is amazingly powerful, but the neck is bendy. If you are interested in a semi-powerful vibrator with a stiff neck take a look at Mona 2 link
. It's not as powerful as the vr6, but it is close.
For a clitoral vibrator, I've had most of the luxury line and tried to make them work, the only one that was powerful enough was Tango link
but it is just too slippery to work well. And putting a sleeve over it, can do the trick, but I've largeish giantish hands, so... it is not that easy for me to hold onto. I usually use the big end of the vr6 on my clit, while another toy is inserted while masturbating for an amazing orgasm that never fails to make me grin. I do plan on buying another vr6 for internal use while the other vr6 is on my clit.
For anal, I would strongly suggest quality silicone toys or glass over rubber or other material. Other materials are fine to explore what you might enjoy, but be warned, they are porous and can cause some issues. And allergic reactions. I love my Bootsy (link above)!!! He is bendy at the neck so he can move with me as I go about doing whatever it is I am doing. I've a few glass toys as well, but they are just not perfect enough as some necks are too small so there is slippage, some have too much of a bulge so removing it is usually a little painful.
All of these toys are REALLY easy to clean. Just use hot water and soap. They are all waterproof.
As for materials to pick from, for me, I only use quality silicone, glass, metal and wood simply because with these materials I have no reactions to them. Even when I was starting out, I only bought jelly/rubber toys to test out the girths to make sure I would find it enjoyable. I used them a few times then tossed them as they usually REAK and you just cannot seem to get them properly cleaned. I also found that after used these materials, my labia would itch and itch and itch. Not a good sign if you ask me.
Hopefully this helps you!! If you have any questions, please feel free email.
