It sounds more like an emotional issue than strictly physical. When was the last time you actually "made love" and not wham bam thank you maam sex?
Hmmm, that distinction has changed gradually. Last intercourse was about 15 years ago.
if she won't let you manually touch her or orally, then have intercourse again, for as long as you can & in as many positions as you can try
to see what helps, and see if her mental or sexual obstacle to pleasure and orgasm, can be addressed.
There's a lot to be said for facing your lover and it feeling more natural and intimate.
