I love fast and hard a lot, but only for a certain amount of time. If it's fast and hard for too long, it starts to hurt and then I'm just like "okay, get it over with already."
Pretty much any position that hits my G-Spot is a gold mine. My current boyfriend is the only one to have ever given me a vaginal orgasm and also the only one to ever get me to squirt! I'm telling you if you want to squirt, learn where the G-Spot is, how to stimulate it, and how to not accidentally stop yourself from doing it. James always looks so proud of himself when it happens! :lol: Plus, it feels really freaking good. If you want tips, find the video "The Expert Guide to the G-Spot", but I warn you that if you don't want to see 2 girls having sex don't watch it. It's all done in an educational way because there's a teacher and a class lol... but it's good. Have you and your partner watch it together and even try along with the video! ;) It also shows you certain sex toys that help you hit the G-Spot. I want to try to find some of the ones it showed... just looking at them turns you on!
As far as a sex toy, one of my favorite is a cock ring that has 2 mini bullets in it. It's big for a cock ring but it's NICE, especially if the girl is on top... you can hold your clit on one of the little "dolphin tails" as long and as hard as you want that way hehe. It's called the triple orgasm cock ring. If you want to see it, it's here: http://www.adameve.com/adult-sex-toys/cock-rings/sp-silicone-triple-orgasm-cock-ring-992.aspx
