Wa `alaykum as-salamu wa rahmatullahi wa barakatuh.

 

There is no problem of reading articles on issues related to puberty and legal rulings of this stage. Almost all scholars discuss those topics as part of their books on Islamic law.

 

Reading articles on sexuality may cause arousal of sexual desire which may cause a person to either commit adultery or at least masturbation. If not, it may, at least lead him/her think continuously about sex. I think it is more appropriate to discuss those issues between a husband and a wife in an appropriate way.

 

Allah Almighty knows best.
