VCF & burning sensation

In a rush last night, my guy and I opted for VCF (lady spermicide gel that you insert like a tampon and inject) instead of a condom. While on top, I had an amazing orgasm, and came *hard.* I squirted with him inside me, and he almost immediately had a burning sensation in his urethra that continued well into the evening (after he came and even after he used the restroom in hopes that peeing would clear it out).

I’ve heard of spermicide causing irritation in some users, but that totally sucked. Has this happened to you or your guy? I can confirm with certainty that neither of us has any STDs that would cause burning sensations.
