It also depends on your male and female so you may just have to wait them out. If both the male and female are both virgins it may take them a while to get used to each other. The female may be being unreceptive to the males advances, or the male just may not really know what he's doing yet since it's his first time. So you may just have to give them time but I definitely agree with this comment ^^^ wait until a storm and pair them up, a lot of people have had success with that.
