I've seen mating attempts many times with this male short tail nurse shark. Typically he will roll or spin around and occasionally a clapser is eventually inserted for several seconds and then it is over. I have never witnessed this behavior before, but it is a different female than usual.
For those shark enthusiasts out there, it is interesting to note that in addition to more than one mating technique in these sharks, this time the contralateral clasper is used. This is a small clip about 40 minutes into it. It took a long time for her to tire and give up fighting. BTW - the female appears to be carrying eggs. This would be her first season for egg laying. My older female also appears to be carrying too. Last year she laid 6 duds.
