Hi Bro,

The lady may be having one of the following conditions:
1. Spasm of the pelvic muscles - this is the most common problem in situations like these. She may have an inner fear of penetration (maybe due to bull-shit stories her grandmother/mother/friends have told her in childhood). Due to this inner fear, she may be sub-consciously contracting her pelvic muscles as soon as she feels penetration. The pelvic muscles are extremely strong, and trying to penetrate when they are constricted can cause pain and damage to the vaginal lining, which leads to even stronger constriction of the muscles, and reinforcement of her inner fear.
Way to cure - alcohol and lots of foreplay. Get her to relax. Maybe play strip-poker to arouse her and prolong even the "taking off clothes" session.Take a couple of drinks. Have a very, very long foreplay session with pussy licking (but NO fingering). While she is aroused, try pushing your tongue in to the vagina. Also, get her to finger her own vagina (If she has long finger nails, put a condom over her finger first). Ask her to beg you to penetrate her (although it's just a game, this will condition her mind that she NEEDS to be penetrated, and that it's initiated by her). Penetrate in missionary position, and use lots of lubricant (AstroGlide is the best). Penetrate slowly, millimeter by millimeter, using constant pressure without thrusting. Be aware that she may still be a virgin (ie Hymen still intact).

2. Vaginal atresia - this is a congenital defect, where the vaginal canal is malformed. However, this is usually detected early in life, or during the menarche. So, this may not be the case.

3. Pelvic osteophytes - these are bony growths arising out of the pelvic bone, which may intrude in to the vaginal area. Can be detected easily by the gynaecologist during the pelvic exam, or on a pelvic x-ray. In about 80% of the cases, this can be corrected by surgery.

Or, the best way to cure her is to intro her to me. I'll make sure she's ready for penetration....lol
