Buy a dildo that's the right size and shape for you.Think about what you want to use it for.Do you want to use it by hand, or do you want a harness?Do you want a vibrator? If so, what kind of vibration are we talking about here? Do you like intense vibrations that will make your eyes roll into the back of your head and have everyone at work wonder what’s going on? Or do you prefer something more subtle with just enough power for some clitoral stimulation during penetration? It’s also worth noting that some dildos can be used as G-spot stimulators (like those from Je Joue) while others are meant primarily as clitoral vibrators (like Lovevib). Whatever type of toy fits your needs best is probably the way to go. You always win when there's variety!
