@cand86: @colorisnteverything: As one of the researchers on the study, I can tell you that we don't know but I have a theory that I call the "globby factor" as water-based lubricants tend to be thicker feeling than silicone based lubricants. However, both actually were linked with high ratings of…

@LiltingLies: Standard KY has an ingredient called chlorhexidine that is linked with burning. In our research study, we tested KY Liquid, Pure Romance's Just Like Me and Sweet Seduction as well as Astroglide (and those are just the water-based products). Good Clean Love is another nice option.

@collegelemur: This is good advice here. As one of the study researchers and a sex researcher/educator/author, I can confirm that oil-based lubes do indeed break down latex condoms. Also, silicone lubricants tend to last longer whereas water-based lubricants absorb into the skin so for long-lasting sex, they may not…

@Moscowinthesummertime: Why, thank you! We enjoy our work.

@say-what: Yes, and to be clear we didn't find that "only" water-based lubricant will do for anal sex. We did find that water-based lubricant was linked to significantly higher ratings of satisfaction for anal sex, but ratings of pleasure and satisfaction were still quite high for anal sex involving the use of…

@thedopeshow: From one of the IU researchers who conducted the study, I say good luck! :)

Congratulations!!

@JeevesofRKdia: I would be happy to, if asked, as there's a bit more to it that could make sex easier and more pleasurable for those interested.

I hope this doesn't sound too self-promoting but I wrote about CAT (and other fun sex things) in my book Because It Feels Good. The thing about CAT is it's the only sex position that's been researched and found to help with orgasm. That doesn't mean that others don't work but few have been tested so rigorously. Enjoy…

love this.

@highjump: Yes, this national sex study is one of our projects at the Center for Sexual Health Promotion. It doesn't sound like the study you participated in was one of ours but, of course, there are other researchers in other departments who study sex, so plenty of possibilities. We're at sexualhealth.indiana.edu if…

@wealhtheow: Thanks for this very thorough description of our work. It's true: we asked about oral sex by gender of the partner (you can find the entire study on nationalsexstudy.indiana.edu)

@autumngrrl: Living together or in a committed relationship fell into the "partnered" (not single) category.

@BioLady: Good question. In one of the papers, we factored other types of contraception use (along with things like partner type, whether they thought or knew of they or their partner had an STI, and several other things) into a larger statistical model to predict condom use.

@miss.terious: We agree that there is a place for sex without a condom. We didn't exclude those individuals but we did ask if they were trying to become pregnant, or if a pregnancy was okay if it happened, etc. So we would not expect, or "want" to see, a 100% condom use rate - and yet, as public health professionals,…

@highjump: Sounds like a different survey (we're pretty active in research). This particular study was conducted over the Internet. I'm not sure which study you're referring to but I'm happy you enjoyed your experience.

@say-what: In this case, our study asked about penile-anal intercourse...

Thanks for covering our research!

@screwtapeletters: Love this! Thanks for passing them on.
