This has to be the best bedroom toy for lesbian couples, we bought one solid and one hollow, if you have a sex toy like bullet vibrator, the hollow one will definitely surprise you, you just need to insert the bullet vibrator into the hollow penis and it can become a vibrating dildo, which is great, the only thing to note is that it seems little thicker, you may need time to get used to it, I believe once you get used to it, come on, this really is the best sex toy for couples.
