A collection of people, as I find them here and there. YMMV

Charlene L. Muehlenhard, PhD Professor of Psychology and Women's Studies at the University of Kansas, she has done a number of interesting psychological studies around college students, gender, sexual agression, and rape.
Charles Moser, PhD, MD Early BDSM researcher and medical doctor to the alternative set.  This link is to his CV, with all of his publications and research.  His book Health Care Without Shame: a Handbook for the Sexually Diverse and Their Caregivers is highly recommended--instructions on how to translate your unconventional sexual practices to your medical provider, and also for medical providers to deal with kinky people.     
Joseph W. Slade - has been studying porn for 25+ years.  He is a professor of telecommunications at Ohio State University. His new book, Pornography in America, is an articulate statement on pornography.  My fave quote from an appreciation page: ""Originally I became interested in pornography because it makes you horny," says Slade.  "I would never want to pretend that my interest is wholly sociological or academic."  Thank you so much for saying this. 
Alan Soble - a philosopher of sex who has done a lot of writing on pornography.  Check out chapter 1 of his current book, Pornography, Sex and Feminism (2002) where he explicitly explicates the diversity of styles in pornography to refute the anti-pornography feminists.  Excellent.
Richard Burt - Now at the University of Florida.  One of his specialties is porn remakes of Shakespeare, and his book Unspeakable ShaXXXpeares has generated some interest.  His courses look at romance novels, among other things.

Hope Weissman - Wesleyan U, women's studies. Teaches "Pornography: writing of prostitutes."

Henry Jenkins - MIT, Communications. Media studies, Women's studies, gender and sexuality; response studies.

Constance Penley - UCSB, Film Studies - "What upsets people is that I study porn to see what it consists of, not to debate whether it is art or deviant."  

Linda Williams - UC Berkeley, Film Studies and Rhetoric

Joanna Frueh - art critic, art historian, and performance artist. Can't find a personal page right now, this link is to her most recent book.
Mary Madden Exploring Cybersexualities website.  Teledildonics is one of her specialties.  Cool!
Meika Loe
A student of Constance Penley. Meika wrote her Masters thesis on Feminist sex-toy stores, and recently published an article in Sexuality and Culture about men and Viagra. Now she's got the PhD and is an assistant professor of anthropology and sociology, plus women's studies at Colgate.
I can no longer find the link to her award-winning participant-observation study at "Bazooms" sports bar. This was her BA honors project, I think. It's quite good too.

BJLand - BJ is interested in Gay Male Porn.  A loving site full of stuff.

Lifestyle Survey
An online questionnaire Survey on Swinging by Jennifer Williams for a Soc class. She's got an interesting bibliography, including an interview with Robert McGinley.

Diane Kholos Wysocki -- Construction of Sex, Gender, & Sexuality:  A Look at the Lives of Male Transvestites.  1996 Master's Thesis in Sociology.  Nice bibliography of Transvestite/Transgender articles and books.  Her recent article in the journal Sexuality & Culture ""Growing up Gay in Rural Nebraska" or a Feminist Relocates to the Midwest" discusses her work as the "straight" advisor to the Gay and Lesbian student group, some of the troubles they had speaking, and the movie that they made, "Growing up Gay in Rural Nebraska."
