Our story: when we first got together we had "lots" of sex but pretty soon I began to notice that she was experiencing pain during penetration. Over the years we tried many things relating to her having vaginitis, bladder infections, etc. There were many years where we might have one or maybe two attempts at intercourse in a year. At least we had oral sex more often but sometimes that was only once every month or two. It was 32 years before the night she made a tearful statement that "maybe you're to big for me" and the light dawned. During that whole time doctors and gynecologists never offered up that possibility as a possible cause of painful intercourse, and I always thought I was average, I am to girthy for her at 6.25".

When I read up about penis size and found LPSG, I got some good advice from BigTwin and others.

When my wife started to dilate her vagina on a fairly regular basis, she started with a 7/8" diameter vibrator and had trouble taking it. She is up to about 1 1/2" diameter now and the other night I got 1/2 way in.

You will need patience and she has to have some interest in sex in order for her to make any progress.

I recommend:

Relaxation
Vibration
Lubrication
Dilation
