My wife is a virgin, she is 28 years old and we are trying to make love, but we can't

Take my word, she is faking to be virgin. She is contracting her pelvis to contract her vagina to make you feel a hard entry. Else, at that age, it is unbelievable that she is still virgin. Spread both her legs far apart, as much as comfortably possible, and enter her in missionary pisition(with you on top). You will be able to penetrate easily, but arouse her sufficiently in advance by adequate foreplay. Use your fingers and tongue deftly during foreplay. If she still does noy naturally lubricate in her vagina, use your spit copiously on your penis and in her c**t and even if that doesn't work, use artificial lubricants like ky jelly. Happy riding, dude. Do share your experience after my advice.
