I Am Obsessing Over Mouthfucking And I Know I Should Not

I have a problem, I am obsessing about being mouthfucked, as in I think more about how I would feel than how my boyfriend would feel. I obsess about gagging, and I should not because I know it's normal but I keep overthinknig it. For a while I stopped overthinking it because my byofriend assured he would not make me gag on purpose, but we had an other conversation about it lately, and since I can't stop thinking about it, it almost kept me from sleeping and even this morning I think about it as soon as I wake up. We were talking about having a threesome one day and how hot it would be (we're gay btw), and we started talking about how we want to be treated if we're in the middle, he told me that he wanted to be treated roughly. I should have found it very sexy but I tend to always overthink things >_< so I said "oh so you'd enjoy the guy ot grab your head and violently shove his cock in your mouth ?" then he said "maybe" and added "I would love to choke on some cock ^_^"

Since I always overthink things, I asked "oh so you enjoy gagging and feeling uncomfortable ?"

We had this kind of conversation so many times, and often I stopped thinking about it this way but these thoughts always come back.

He told me that I'm the only one he knows who thinks it that way, who's scared of it, I shouldn't even care.
I agree with him, and I know you will all agree, because it's super hot to give a nice blowjob and to deepthroat someone, I like it myself.
The problem is that I keep overthinking it. Since we had this conversaiton, yesterday evening, I kept thinking about what he said "I would love to choke on some cocks".

Maybe some part of me keeps wondering "does he love to be mouthfucked and give a lot of pleasure, and gagging consequently because that's how it works, or does he just like to choke ?"
This question is really stupid, I admit it.

I would like you to help me overcome this, I know myself that I should not think about it that way, moreover I acknowledge that it's hot and I really wanna be mouthfucked by him, so it's not very logical...
How could I stop overthinking this? Because it's not worth it and it's retarded to think about it that way. I use not to think like that.

 

I talked with my boyfriend and I don't have any worries about all this anymore^^ can someone delete this topic ? x)
