Are you able to touch your partner in a loving, yet non-sexual way?
Touching that ONLY leads to sex is a common complaint for many couples. I'm assuming you are a guy?
I would try to be loving & touch intimately (but not sexually) for a period of time & see if it leads to her initiating sex. Say a month, if you can stand it.
If nothing gets better, then you two aren't compatible & you should move on.
Second thoughts can generally be amended with judicious action; injudicious actions can seldom be recovered with second thoughts.
