Sometimes my boyfriend gets tired and I take over on top but when I do my vagina for some reason gets super dry and all the dry sex burns my vagina. What are some best sex positions for girls to do?

Edit: Our normal sex positions are missionary, me laying on my stomach and having my legs closed while he is on top of me, cowgirl and reverse cowgirl, and sometimes I have my legs up on his shoulders but that makes me scream so we can’t do that lol.

And we also do doggy style
