BP's can breed for 20+ years...so no worries on that score.
As to the wisdom of buying a relatively expensive snake so soon after getting your first one ever...that's really up to you. If you feel like you have the husbandry issues dialed in fine, and feel completely confident in caring for the snake you have now...then buying an albino should be fine. Their care requirements are identical.![]()
As for male or female...that's also up to you and your preferences. Females tend to be more expensive 'cause they're the ones who lay all those lovely eggs. A lot of people will go with choosing the male as the visible morph, and buying a female het for that morph...as a less expensive way to get morph babies in the future. But you're the one who best knows your own budget...plans..and preferences.
