If and I say IF, Huskerdust is canon (because i swear to god if they are not-). Regardless of angel's "experience" (if you can call it that), once they do "it" he would be cumming easily.
Imagine, Angel, being confident in his abilities, would be nervous once husk starts kissing him gently, asking him if he's comfortable, if it's okay with him. Husk, preparing Angel so that it would not hurt, and Angel just, cumming, because he have never done it so slow, so full of passion, so gently. Angel tensing up when Husk asks him if he's ready and Husk noticing and stopping and asking Angel if he's alright, if he wants them/him to stop, if he needed time to prepare himself (mentally or emotionally). Imagine Angel being overstimulize, cumming easily, getting shy and flustered, acting like a virgin, because Husk is treating him with love, passion, and respect. The consent that I know Husk would be asking for.
Imagine the aftercare. Husk taking care of angel after he pass out (or not), just Husk taking care of Angel after, cleaning him, tucking him in, cuddling.
