Very valid. Ngl, I had no idea where that sex scene was gonna go and I have this weird thing that even when writing porn I'm like "nah, that's too unrealistic" and since I came up with the virginity dialogue early on, I ended up working around that. So, I felt like doing anything not vanilla would be too wild for his first time xd
you'd be surprised what guys like that are open to, even for their first time! actually i think they might be more open BECAUSE they're new... don't know what they like yet, want to be directed, etc... (for the record i'm not talking out my ass, i'm married and have been with numerous guys like this) but i do understand writing what you know, of course. writing sex scenes is hard, even when writing a scene you've basically already lived irl!
