Is it normal to never kiss in a relationship?
Depends.It depends
Yes, some couples never kiss, and that can be perfectly fine if both people are happy with it. If one of you misses kissing, it’s worth talking openly about what each of you wants.
Some people simply don’t enjoy kissing, feel awkward about it, or show affection in other ways. Couples can have loving relationships without kissing, as long as that works for both of them.
If you want to kiss and your partner doesn’t—or you’re unsure why it never happens—bring it up gently rather than guessing. Different preferences aren’t a problem by themselves; feeling pressured, rejected, or unable to talk about them is the part worth paying attention to.
