Is it only intercourse she is not interested in? If so, that sounds like the issue does not involve a lack of desire or need for intimacy with you. You need to talk to her, make it clear that this is an issue that is important, and promise her you are open to anything she needs to discuss. Good luck OP.

Providing her definition of foreplay includes ******** etc. then ok I suppose.

If she's not willing to change then the worst thing you can do is try and convince yourself that's just how you'll have to live. You can always try and fix your marriage but you should never settle, there is way too many people out there.

Dude she's doing one of those crazy woman tricks to mess with your head. She wants to see if you really love her or if you're just there for the sex.

did you tell her that the only foreplay your interested in is watching her make you a sammich?

Tell her no foreplay, and find another partner

If you're circumcised, you should look into Foreskin restoration. Many women experience pain and dryness when having sex with circ'd men. It helps men too...

This is an awful situation. I suggest you to have a serious talk to your wife, making sure that you deeply love her (I assume you do, because you've been married to her for 13 years), but you can't live without sex.

Time to dump her and date

Not to sound rude but it seems like she's: a)might be cheating on you or b)may be feeling/realizing she is a lebian. Hope you fix it.
