Threesome...😳

Ashley
Hi!
So let's just get into it lol My boyfriend and I were laying in bed talking about trying new things and he suggested a threesome with a girl  ( of course ) and not that I'm against it I'm always down to try SOMETHING new things. I just have never had a threesome before ... I wouldn't know how to start that .. Who to find, what to say ... It just seems a little awkward lol . 
Please let me know if you have any suggestions of what to do or maybe and other kinky sexy ideas !
Thanks for reading .
