Can condoms make erectile dysfunction worse? Last time me and my boyfriend had sex he couldn't perform, first time ever. then tonight he said he forgot to put the condom on. I said put it on we don't want a baby right now. He goes "are you sure we're not having too much fun" and keeps going so I'm like we really need to use one. He put his weight on me and said "get a condom then" and doesn't stop untill I grabbed one and held it out to him. He's never acted like that before, so I'm wondering if he was worried it would happen again... Chances of being pregnant from that are pretty slim right?
