Beginners silicone dildo

I want to buy a first dildo for my girlfriend. Am not sure whether to get the Lovehoney Satisfy Me Curve Silicone Dildo or Lovehoney Satisfy Me G-Spot Silicone Dildo. Her vagina is on the tighter side. Any ideas? Thanks

If it's between those two, and she's on the smaller side, I'd definitely pick the Curve. I know from personal experience that 5" circumference silicone toys, like the G-Spot one, can be a bit much at times.
Plus, it's purple. That's always better =P

Thank you so much, that's really helpful! :)
