Seriously they're fun. I had my reservations cause i know my tounge can't pulsate at whatever rpms, but then i had my girlfriend ask me to play with myself while she used it and it was the biggest turn on!!! Also bring them on road trips!
I dunno if girls "prefer" it. I mean i guess some might. I think it's a time thing sometimes. By no means would i go for a toy over sex but I mean if i could strap on a toy that jerked me off in record time..........
bring out on a date with you. during dinner, and if its quite enough, place it by her legs under the table. doesnt have to go in or anything, but her feeling the vibration while eating dinner will make her go crazy. tease her and youll get 100x back at home
