Husband & I Had Intercourse Today, Was The First Time

Husband & I had intercourse today, was the first time we've had intercourse in about two weeks. Anyhow I wasn't dry & was very wet. At the beginning of intercourse i noticed something of a white/brown flakey crumbs or something on his penis that came from my vagina right after he inserted himself into me. Just wondering what it could be? There was also some dryed brown cum like substance in my panties before sex?
