I'm a total shipper and have been since I was teeny tiny, even though I didn't know it obviously! Ever since I can remember I have watched a show and wanted two people to be together more than anyone else; from Zack/Kelly in Saved by the Bell to Sabrina/Harvey in Sabrina to Kimberly/Tommy in Power Rangers! I can vividly remember being devastated if and when they weren't together and having an irrational dislike towards any other person they were with that I didn't like!
It wasn't until I came here, however, that I knew it was a "thing"! But yeah, I can watch nearly any show (not all obviously) and I will pick out a couple that I will champion. They tend to follow a very strict pattern where they are the first couple to be together, lol. I very rarely budge.
My ultimate ship ever is Lucas/Peyton from One Tree Hill. They're just...IT. They define everything that love should be, as well as some things it shouldn't, but I never said they were perfect! I'm yet to find words to say why they're my OTP.
I was a big Stefan/Elena fan until I stopped liking Elena and decided that both the Salvatores are way better off without her and should just go be happy, bitchy brothers together!
Others include:
Buffy/Angel
Sydney/Vaughn (Alias)
Ryan/Marissa (The O.C)
Sandy/Kirsten (The O.C lol)
Max/Liz (Roswell)
Joey/Eddie (Dawson's Creek - this is the one that scuppers my other perfect pattern lol)
Rory/Jess (Gilmore Girls)
Lorelai/Luke (Gilmore Girls)
Rose/Doctor Who (DT only! 😛)
I could go on with every show I have ever watched but I needn't, I think you get the picture lol.
Bizarrely, considering relationships are such a huge part of my televison watching experience, you will very rarely, if ever, catch me even entertaining an au/non canon ship...
