Hello friends - looking for a specific manga~

It would take me a few hours to search through my lists, but I'm looking for a really cute, yaoi manga . it's complete. And has a uke who doesn't know what masturbating or porn is.

The seme learns this and helps him jerk off at his house.

The uke tries to do it himself but can't. And the seme helps him again.

No color, japanese origin.

They're in highschool, I think the uke has the light hair.

If you happen to know the title of this one please help out a friend.

Thanks so much!
