Hey, why be on the defensive?
I like PxTouma (...and HokutoxP), but for similar reasons to IorixP and MikixP. Who doesn't want to see an easily-flustered P-rotagonist saddled with a lovable, manipulative, slightly sexy but intensely flawed girlfriend/boyfriend? It's called classic comedy stylings. And at more serious moments, it can be a turn-on, too.
But it doesn't mean that in an alternate fictional realm, Touma can't be the eternal lifemate of our own Clear Blue. Warning though, Clear—Shouta is jealous and told me he's going to disguise himself as Touma and take his place. I warned Shouta that he was the wrong height for that, but he blew me off. Kids today...
Because she's really afraid that I would kill her. (And you're just on the border of becoming meat here.)
Same with you, all girls from Idolm@ster can't age. (Unless they need to.) You, otakus and your (imaginary) waifus/husbandos...(Sorry if I'm rude but I really want to say that.)
Sorry though, but Shouta looks up to me like a big sister. He maybe a fussy little boy but he's pretty cute.
I'm sure everyone has their own alternate realm in which they can be with Touma. But in Clear's realm, poor Shouta...I'll date you! <3
Since we're talking about PxTouma I decided I might as well post some JupiterxJupiter pics to erase the thoughts of PxTouma for some of you all. 
Sorry but in my realm, Touma's with me, Shouta's with Yayoi and Hokuto's trying to hit on Makoto/Azusa.
Ikuto, I don't think you're really helping here.
Sorry, Clear and Hitsuji. I didn't like what I just did either. If it's any consolation, I don't sail that ship, not even for a crack pairing. D: Call it my religious upbringing or whatever, but yeah. I'd try to explain what goes on in the land of the shippers, but Ikuto already had done that, so yeah.
It's alright. It's not your fault.
Same with you, I don't sail that ship either. (Crack pairing are too crazy for my taste.)
