Wanting enjoyable sex

So me and my boyfriend have had sex before but idk if you’d call it sex. He wears a condom (and I’m on the pill) but it seems like I’m super tight. So we use KY water based lube but every time I use it, there is a burning sensation. We tried it without the lube and it didn’t burn as bad but still did some. Any tips to make sex enjoyable? He just puts it in and takes it out while I try not to cry... I know it’s normal to be tight but we’ve had sex for awhile it is just never enjoyable.
