Maria and Tracy couldn't be more different. Think the builder Charlie went out with Maria as well as Tracy too

They are quite similar.
Tyrone has the most varied taste, with Maria, Kirsty and Fiz.

I suspect Tracy's motive for being with Luke is the hope Robert will be jealous and want to get back with her.

I think they will be fun to Watch.

Many soap characters have varied taste to be fair, seeing as they're not allowed to be single for too long and must be paired up with one of their neighbours asap

Gary also has varying taste, Izzy, Alya and Sarah.
The only consistent one was Jason who went for typical dollybird types the whole time, Rosie, Eva, Candice, Sarah.

Let's not forget he tried it on with both Carla & Katy Armstrong too!

Yes Charlie had an affair with Maria & that was Tracy's sole reason for murdering him!!!

In Jason's case, it was believable that he would go for them and that they would go for him - unlike Maria and Tyrone, when she normally goes for guys like Liam, Luke, and Aidan.

Maria & Tyrone wasn't unbelievable at all though because when they first went out they were pretty much a match!! It was when Maria was still just a rather scruffy little kennel maid whos idea of fashion was 15 different colours of polo shirt & jeans!!
It was only after Ty strayed with Fiz & Maxine took Maria under her wing that we saw the more stylish & sexy Maria that we know now!!
The bond with Tyrone was made back in those early days & neither of them have ever lost it!! Their second spell as boyfriend/girlfriend was rooted in the fact that Maria MK2 was constantly getting herself into hot water of various kinds & a still besotted Ty was always on hand to bail her out/comfort her!! It was all actually rather sweet & quite believable at the time & I think would still be believable if they were to reunite them now!!

Characters have anyone as long as they have a pulse.

Sounds right

"Varied taste" = not fussy - at least on soaps.

Didn't Jason date Becky too?

Is there anyone Jason hasn't had a go with (apart from maybe Emily)?

But yes you are right, he was with Becky and even got engaged to her.

Don't forget Jason had a one night stand with Gemma lol

Why is Luke even on the show?

Because he's a actor.

He's not, he's a character

Jason had a fling with Eva's mum Stella as well

And at one point it looked like Luke might have taken Audrey up on such an offer, had she made it. They even went on romantic country walks and drives together.
Mind you, Audrey has varied tastes as well. And no end of men throwing themselves at her.
Age is not a barrier, I'm not wrong, am I Gail, hmmm?

The real life actor is playing a character same thing.

Didn't Jason even try it on with Gail once

I heard rumors that Jason was so busy with the women on the street he used to just lift them up in the air and when he let them down their legs would be inside his boots. I don't pay heed to such nonsense but when I think back i never saw him without those boots on.

Tracy. Who'd have thought he would have more sense than Luke

This is seriously the worst pairing ever. It shrieks of desperation from the show and is a perfect example of how out of touch and completely unrealistic Corrie has become

Seems like Ryan Connor all over again.
