Of course use my lovely rabbit vibrators and bullet eggs. I really enjoy my solo play and play with my husband.
If I want to go natural, two fingers round the base of my clit, side to side mostly. If I want to multiple orgasm and squirt, nothing like a power wand. My favourite is the Moregasm wand from Ann Summers (it's a UK sex shop).
I prefer to just use my fingers, like I've done since I was young. Start out gentle and slow, massaging my clit and eventually working my way inside. 2-3 fingers, depending on how turned on I am.
