There it is the big question. I mean the only females he's close to is Mrs. Puff and Sandy. And he would rather get a little to friendly with Patrick and Squidward.
I dont know about spongebob being gay but in one episode when spongebob tries to give gary a bath spongbob grabs to bars of soap and says that the two bars of soap are dublooms and says to gary "Look dublooms, dont drop them." And in another episode when Mr.Krabbs wants to go partying with Spongbob and Patrick. The first stop was The Wash which was a landrymat. First Spongbob says "Hey guys, Spongbob is back." Then Patrick says "Lets boogy." Finally, Mr.Krabs says or sounds like he is saying "Any porn in the store." So, next time you see those two episodes you should pay close attention to them. How should I know, well I have a three year old sister
I think he wasn't before...but did you see the episode where he and Patrick run and eachother in slowmotion, hug, and then spongebob jumps on patricks back for a ride? Come on.
Also, they hang around eachother in their underwear way too much, nowadays.
