Not really la, sometimes there are some condoms that have
special design that can give you better sensation and etc,
etc...
In Singapore not so much available, but overseas they are very
common.
I bought some US Durex condoms at an online store in SG http://www.sgintimates.com
Erm, cons of buying online is have to wait a couple days la.. but
quite ok la if you stock up in advance! HAHAHA...
