I suffer from premature ejaculation. when my wife and i have intercourse when she is on too normal i can last long but when she squats on top and is in reverse i cant last and feels tighter. why is this? arent they the same positiona ideally?

The position described may also be preferred for your partner, and will cause more contact with the pubic bone near the clitoral site, which may be why your partner prefers this position. This will create more stimulation of the lower portion of the shaft of the penis, and contribute to quicker ejaculation in the male.

It is difficult to tell. Suggest stick to any position you both enjoy
