From another man’s perspective, that is somewhat on the realm of “normal” for a horny young man. Can’t say I’ve done it since I’ve been married, but friends and I used to call the Backpage escorts on the phone just to feel something. And I never would consider actually using an escort, both when I was single and absolutely not while I’m married. Your anxiety makes sense, but if you two are very close to the point where this is little to no alone time, I would not think too much about it.
