Relentless attempts to mate, haha

Another quick question, since adding my new acquired male (about 4.5″, 3 or so years old) to my female (about 4.5″, almost 2 years old) the male constantly harasses the female to mate even though she is well under the age/size of sexual maturity at this point. I understand he is just doing his thing and it is to be expected, but will he cease eventually, getting bored or tired of this or will he chase after her until the deed is finally done a few years from now? Haha. I know in nature they kind of just “meet up” and move on. I have never had to observe this in a captive setting. It’s pretty amusing actually and luckily she seems to stand her ground and he isn’t being aggressive in the process.
