Yes you should wear a pull up.
Once you start wearing pull ups you'll begin to like them if you don't already.
If all you've worn was a pull up then you'll be even happier when you try on an actual diaper.
Although pull ups are good and fun to wear the actual tape on diaper when it is put on and wet will feel even better.
I started out wearing pull ups and then decided to try on some baby diapers and after trying on baby diapers I was even more of a diaper lover.
I wish I could wear diapers all the time but cannot afford too.
If I could afford to wear diapers everyday and all the time I would no longer use the toilet and use diapers.
Not sure of your age but if you're a kid you could try some Gentle Steps size 7 diapers which are awesome and feel great when wet.
Even some adults can modify them to somewhat fit in them.
However adult diapers are even better if you can afford them but for those that cannot afford adult diapers then some toddler or largest sized baby diapers are better than no diapers.
And of course pull ups are good too but the actual diapers are even better.
