I think part of the problem, and I know I'm harping on this because I've brought it up before, is how much we have to infer from him due to his largely mute presentation. Because we don't hear his response to the sex acts he encounters we're left to make assumptions based on whatever emoticon N_Taii chooses to use.
I take his lack of forwardness when it comes to sexual activity as due to a lack of exposure to it as a kid. His parents died too early in his life for their affection towards one another to have influenced him and he was literally raised by a nun in a church and the only reason Cyanna is more comfortable with sex than Leto is because of a certain rapist pressing on her. I take his abnormal patience with not having sex with Rose as respect, from his extremely limited perspective of the events that happen around him he has no reason to believe that she's getting stuffed daily by the duke, and to avoid scandal he keeps things chaste since he's a secret boyfriend after all. Because Leto doesn't communicate directly with the audience we never see what he actually thinks, which means his responses will always be limited in what they can show us. He's a step up from Noa, who was a step up from Casio, but he's still pretty bland overall due in no small part to his muteness.
Personally my worry about Leto's sheltered nature is that N_Taii is going to replicate an event from HC1 and 2. At the end of both games deus ex machina is employed to bring about the defeat of the villains, which includes magically bestowed sexual prowess in one and hyperbolic time chamber fuck training in two for the bad endings. I'm not worried about an overall lack of sexual tension and I can overlook his constant befuddled response to sex happening in public, but it's going to be really hard to take him seriously on the revenge endings if he's going to start domming women who by that point are going to be way more experienced than him, so I'm worried that the ending is going to be unearned... again.
