New to sex help ๐Ÿ˜‚

So I just lost my virginity to my new husband a few days ago (weโ€™ve done it about 4 times since) thus far- everything has been pretty amazing, but a lot of the positions I thought Iโ€™d be interested in donโ€™t feel too good ๐Ÿ˜… (Like him going in from behind)

Does it get better over time? Do we just need to figure out an easier way to make it happen??
