Imagine Natasha referring to steve as her "gay best friend" all the time, and while he is flattered that she thinks of him as such a good friend (maybe even best friend) he is also really annoyed because he has, repeatedly, told her he is straight!!
"Natasha I am not gay. Just because I like to take it slow and wait until I’m married does not mean i’m not attracted to women."
"But Stevie Sweetie, that could just mean that you are Bi with an inclination to males and have female attributes is all, its nothing to be ashamed of!" Natasha was still walking towards him with the pink shirt that said "Sorry girls, I’m gay".
Steve walked out into the living room, neutral territory so this talk would have witnesses. Only Tony and Thor were there to witness this however, not the back up Steve was hoping for, but at least there is some back up.
" No Nat, and I’m not still ‘finding my sexuality’ either!"
Natasha was shaking her head still with a smile, ” Steve I have never met a male that was able to look at a fully naked woman and not be effected. At all. Don’t try to say that I didn’t see all of you, because you were naked too.”
Stark perked up at this and looked at him for conformation, Steve just hung his head. ” It was an accident Tony! I swear I just forgot my towel!”. Stark started to giggle.
" How sure are you, Cap? You know its okay however you feel or choose to try." Stark was able to get out between giggles.
Steve just sighed, ” I’m sure. Very Sure. It’s not like I haven’t been exposed to all forms of sexuality. Damn it Natasha, other than that embarrassing event you had to mention what makes you believe I couldn’t be attracted to just women again?”
Natasha was silent for a bit before rushing though her answer, ” Well, you always let me take you shopping and we work out together and never make comments on my body unless I asks you or flirt even good naturally. I love being friends, but I don’t want our friendship to stop you from finding love either….okay!”
Steve took a breath and through the T-shirt to the ground so he could hold her hand before answering.
"Natasha, you are my friend and I love you. I’m glad our friendship and my happiness are important to you, but you don’t have to worry about ruining my "chances". When I find someone, I doubt our friendship would ever get in the way. In fact it can’t because then she wouldn’t be the one, okay?"
Natasha nodded, then bounced back with a little with a grin asked, “Does that mean I have to get rid of my “With my GBF” tank ?”
"If it means gay best friend, please just shorten it to best friend.", Steve started to walk away from Natasha both happy and annoyed with the situation.
