Condom movement

I've noticed that the condom tends to slide up (Towards the head of the penis) the shaft during the outward stroke (lack of better wording). When I reenter the vagina the condom tends to slide back down the shaft. Is this suppose to be normal? If not is this increasing the chances of pregnancy?

Are you applying lubricant to the shaft of the penis? If so, do not. Only apply lube to the head/glans in order to have more wiggle room for added stimulation.

What size condom are you using? They are generally available in small/medium/large so you might try going down a size.

no additional lube on the shaft other than from oral sex. I'm not sure what size I buy, the packages don't say, so I'm guessing they are the standard medium size?
