Credence is incredibly touch starved, he's almost never been touched before in a way that wasn't painful, let alone by someone he found as attractive as Newt. This has the unfortunate side effect of causing him awkward boners every time Newt touches him, which he prays Newt doesn't notice. Newt does and asks if Credence wants him to do something about it.

Bonuses (would be cool to see but won't be disappointed if they're left out):
- Credence coming quickly but being able to have multiple orgasms
- Some internalized homophobia on Credence's part
