I need HELP again!!!!!!

You know there was this one manga that was really bitter at the beginning(and the the end too, for me, but it has happy ending. The story was like a straight man meet a gay man, the straight man was somewhat protective of the gay man, and later fall in love with the gay man (the gay man had a history, where in the past he fall in love with straight man but the straight man couldn't get it up cause it was disgusting and he's still trying t recover form it) And when they decided to move their friendship to the next level(they already kissed a bunch before deciding this) but when the straight man saw the penis, he show a 'disgusting' face on and couldn't move. The gay man was so shock and angry at himself for not realizing that a straight man just couldn't get it up with a dick. Not long after that they make up and tada ~~~~~Happy ending.

Extra information: the straight man and gay man meet at a restaurant of the straight man. The manga start with a hungry kid looking for food in a trashcan when a man found him and give him food(actually it was a soup, I think). Years later on it was revealed that the soup was first made by the son and when the lost-man-who-was-trying-to-eat-the-trashcan-food-in-there eat it and cried: saying that it was so delicious. And that young son gained the confidence in himself to do business with his father.

Okay they might be not the same story but those two have been on my mind and if you happen to know of it(like easy tags) please give me the link. Thanks :)
