My male pastel would lock up with my arm given the chance last year, but wouldn't touch a female when I tried this year, He finally got going a few weeks ago, but still to this day wants nothing to do with my spider (mainly cuz thats the girl I really want him to breed) but think your issue could be just the fact those two dont like each other or he really hasn't got everything figured out yet, either option is completely feasible. But I would recommend that you just keep trying.
