I'm no expert but I've had a g/f who had a similar problem. If your b/f really loves you and cares for you, you should be able to talk to him about your anguishes and he should help put you at ease and be very gentle and careful with you. If not, lose him!I am a virgin and I'm so worried about the first time I have sex because I'm so tight...I can just about fit a heavy flow tampon up there, but that's only like a 2cm diameter or something. I once tried to put my finger up there to try and break the hymen but it just hurt like hell and I'm never doing that again. Really worried now because I want to have sex with my boyfriend but I'm petrified that he won't fit in me, or it will be agony...did anyone else have that problem?
If that doesn't help, try asking to see a female nurse at your GP. They've seen it all/heard it all so there'll be no need to get embarrassed about anything.
