Well, it does take a bit of coordination - but it becomes really natural. To me, it doesn't feel like it's hard work, but I think in the beginning I had to get a bit of a rhythm down. Now I really prefer to use 2 separate toys, because I can control the stimulation more so my clit doesn't get overstimulated or too sensitive. (Which allows me to have more multiples.)
The Liv seems like it would be a GREAT first penetrative toy. The girth sounds like it would be a nice place to start too. That sounds like a really good option - plus it has really high quality materials & should last you a good long time.
The Zini Seed sounds like a good option if you don't need a ton of power. It's rated 3 vrooms out of 5, which definitely doesn't put it in the power queen category - but it is quiet, which is a plus. If you're interested in something that runs on batteries and is a bit stronger (4 out of 5 vrooms) but still quiet, you might take a peek at the PicoBong Ako
as well. Or, my personal favorite the Je Joue MiMi
, which is another rechargeable, fairly powerful, quiet clitoral vibe.
There are so many options, it can be really hard to decide. But the searching can be oh so fun!
I'm sure others will come along with some GREAT suggestions too, and maybe they'll be able to help you narrow down your choices.
