If she doesn't wait until marriage she's a whore. At no point should a woman demand anything sexual from you.

i have the same problem OP. ACE 8/10 here, the only diff is that first relationship give me suicidal thoughts in second i feel deeply humiliated because this girl gave me fragment of her hair (i have hair fetish) but due to stress i failed this.

i read some books and i fixed own mental state, partially emotions (Emotionally Focused Therapy) but my body still try protect me, so i try Somatic Experiencing too but i can't find any therapist which do this.

You can't and won't breed. It's what nature wants, don't resist it.

Same situation OP except I never had one relationship. I don't think it's possible to overcome at this advanced age, just accept your situation and the way your brain works. That you're not compatible with the opposite sex. So I've moved to a peaceful rural location with precisely 0 legible bachelorettes or any prospects for romance. I choose to live alone, but I'm not lonely. Secure job, peaceful surrounds, lovely.
