To me it's like who cares what people are gonna laugh at you when you're kissing your opposite gender? I never understood it.

I don't want to kiss in public. PDA has always been weird to me. It sickens me when I'm single and I don't think I'd like it if I was ever with someone. Plus I know how it feels to see it everywhere and I hate that feeling so I don't want to add to it.0

Could be many reasons.
They're embarrassed of their partner
Don't agree with PDA
Might think it's inappropriate out in the open space at the time
Might like attention given to them by passerby's (kissing = instant no-attention from opposite sex passerby's basically)
