Can oil-based lubricant or oil impair the latex condom? How?

I had sex next to my boyfriend (I'm 17, he's 18), and he used latex condom. Well, we have water-based lubricant, but he also used the Virgin Coconut Oil (I know you might roll with laughter because this is not really supposed to be on the bed part... and it sucks I smelled of coconuts) but, he found a bottle and used it to press me, and he used this on my vagina, but I couldn't remember if inserted his fingers (with the oil).

I read that oil or oil-based lubricants cannot be used for latex condoms. They damage the latex segment and lose its effectiveness? How does it in reality "lose" the effectiveness? Like, does it put holes surrounded by the condoms?

I am really worried I might be pregnant after months.. We used condoms the whole time we have sex, and the only time we didn't be that when he was trying he insert his penis lacking condom but we decided not to..

I'm worried. Do you come up with I can get pregnant?

Oh yeah, supplementary information, it's my 1st-2nd day after my menstruation.

This is one of your least fertile times, so you're fine. It's petroleum base lubricants (like vasoline) that damage condoms. I don't know just about oil base because they do make grease based sensual rub oils.

I hold a unhealthy craze with my computer?

Oil base lubricants break down latex. Basically they make latex meagre which could mean at hand were tiny holes but also it would be more susceptible to breaking.

Post partem/ please back?

As little as sixty seconds' exposure of commercial latex condoms to mineral grease, a common component of mitt lotions and other lubricants used during sexual intercourse, caused approximately 90% fade away in the strength of the condoms, as measured by their burst volumes within the standard ISO (International Standards Organization) Air Burst Test. Burst pressures were also reduced, although smaller number dramatically. Lubricants such as Vaseline Intensive Care and Johnson's Baby Oil, each containing mineral grease, also affected condom integrity. Five min. exposure of condoms to glycerol, a frequent component of appendage lotions and 'personal lubricants', did not significantly affect burst volume or pressure. Aqueous nonoxynol-9 spermicide did not affect either burst index.
