bubbles between shaft and condom

[Dedcenter10]

Hey, I just lost my virginity last week, and I've been very careful with the condoms we've used. SOmething I've noticed are these little bubbles between the condom and my shaft, trapped in there. My question is, is that lubricant or could it be precum? I tend to precum a lot when she gives me handjobs or we're just fooling around. The condoms are very snug, but could precum theoretically 'sneak' out of the condom along my shaft and out near the base? And if that were to happen, do you think it will be able to get in the vagina and pose a possible pregnancy threat? I'm just needing a little reassurance because I worry about stuff like this. Thanks to anyone who has advice.

is it air bubbles?
I mean doesn't matter how much precum, its going to be filled full of cum eventually...you know? That's why you withdraw as soon as you do cum, and hold the base of it so it doesn't slide off.
Also, when putting on a condom, be sure you are pinching the tip of the condom so that it doesn't get any air pockets in there.
