Being too tight is sometimes really a pain in the ass. I've had to spend some time pre-fucking myself with a toy prior to going on a date that I thought would end in sex. I've had to turn guys away after finding out how monstrously endowed they were. I love doing that with them on their back and me on top of them. Even through a layer of panties / boxers it is still awesome.
If you can't fit a Jehovas Witness bible in your ass or a 2 volumes of Encyclopedia Brittanica in your snatch...
Easy, buy a dildo that is an average length for a man (6") and try it out on yourself. Then buy one that is 7", then 8", etc. By the way, kegels are good for guys to do too, all you guys listening out there.
No girl is ever happy! So many girls are so paranoid that they're not tight enough. I am so tight it's unreal. My boyfriend and I have regular good explosive sex, and I'm still super super tight. We really have to work our way up to sex with a lot of good foreplay, so a quickie is always out of the question. Sometimes sex is impossible, it can be a chore early on just to get a finger in. It's hard just to get the muscles to relax. Once there though, the sex is amazing. All the same, I'd love to be able to control these muscles a little better.
