One proposed addition to DSM-5 has been Hypersexual Disorder. Formerly, it was being proposed by the Paraphilias Subworkgroup for inclusion as a new disorder, and they have now retreated from that somewhat, and the Sexual Dysfunctions Subworkgroup is now considering including it in the appendix. (All this was made public with the recent revamp of the dsm5.org site).
On this subject, there was a recent article on asexualnews.com titled Asexuals should worry about the inclusion of hyperactive sexual desire disorder.
I wrote a follow-up to this (also on asexualnews.com): Hypersexuality in the DSM: A threat to constitutional rights and copy-pasted it in the feedback section on the dsm5.org site.
