Can’t have sex ??

So I’ve recently lost my virginity and only had sex that one time. Today me and my boyfriend were alone but when he was hard I wasn’t wet enough and vice verse. As well as this when we get the condom on his boner goes away . I also can’t help but giggle during this situation bcoz it’s just so Un sexy lol

Is this normal ? Is there anyways we can actually make the sex sexy instead of just something funny ?
