You have no idea how much skinny guys hear this haha. I’m sure you mean well by it but at the end of the day you’re making light of what is a struggle for a lot of people.

With that being said, if the financials are there then yeah OP should be building some muscle. I personally needed to be on 3000 calories a day to gain any weight at all. But I swear gaining 20 pounds (8 or 9 kgs) turned my dating life around unbelievably fast.
