If you can tell me the name of this manga it would be awesome of you...

In this yaoi manga, there were two guys and one of the guys in an attempt to show his feelings to the other guy gets off using his leg. The guy whose leg the other one gets off on, gets a hard-on from watching the other get off. They were both involved in some sort of martial arts lesson earlier that day.

Also, if you know of any yaoi mangas where one of the guys gets a hard on, without the other guy doing anything and is embarassed and does not want the other guy to know and the other finds out without liking the other guy first, then falls for him later. Please tell me titles!!! Thank you! 😀

That sounds a lot like Living for Tomorrow.

I would also recomend Hoshigarimasen! Katsumade wa. It basically fits the description of what you are looking for.
