Yes, you can use lubricants with condoms. Please be informed that condoms are lubricated during the manufacturing stage.
So, the condom that you buy already has lubricant on the outside, inside or both. If you still want to use lubricants to make your affair a gliding smooth, you are advised to use only water-based or silicone-based lubricant.
Oil-based lubricants (such as baby oil or petroleum jelly) are a big NO-NO as they can react with latex and weaken it.
Please see the instructions carefully before choosing to add a lubricant over the condom.
