Proof of Sex

"I had sex with her"

I committed this activity called sex, which
is not ordinary, not day-to-day
yet quite intense

This is the fact

But is there any proof that
I can show to others? To myself?

---

If it's other activity, like
"I visited that place with her"

probably photos exist and I can confirm it & share it with others

But sex
no such "physical" evidence, or reminder, that
I can still see, still touch & still physically feel

---

Sex between me and her certainly happened
at some point in my life & in her life

But nobody can prove

Now
it exists only in our memory
