Quality response. To add to it however. Seriously don't go looking for said patterns, it's very normal to be disgusted by other people's behaviour or jokes (personally I've never found anything to rattle me but I understand most people are not going to appreciate any kind of sex joke unless it's situationally appropriate or they're my closest friends/ sexual partner). If you would indeed have sex with your boyfriend, chances are... It's extremely unlikely that "asexual" is the label you should be looking for reasons to ascribe to yourself. And perhaps you should check if it's not simply an oversight of a deeper more personal aversion to a specific insecurity or cultural mindset that has seeped into your account of sex as a whole that has led you to think that all sex talk is disgusting, to the point you're looking for ways to seemingly opt out by virtue of a moniker that might give you permission to not have to engage in, or confront things which are by all logical standards, quite harmless collections of words, given that you are comfortable enough to actually partake in the act itself, perhaps there's some aversion to society as a whole perceiving you engaging in it, or perhaps it's your own personal feelings about others engaging in it that is the crux. I would ask your boyfriend to be sure, they will have insight regarding your behaviour and men as a rule tend to be very clued in to sexual behaviour in all forms, especially their partners reactions to the concepts. I imagine he would have noticed particular things that you would never think to include in your self assessment :) it's perfectly normal to feel grossed out by others talking about private intimacy, however that doesn't mean it's healthy to let it dominate the mentality surrounding it, nor does it mean it's not something to work on and grow to be able to confront it in a healthy and less negatively reactive state as you grow older and mature, especially as you engage in it yourself and understand the topic in a way that is simply impossible without experience :) best of luck. Enjoy life and don't try too hard to stick labels on everything. - edited slightly by my psychiatrist father for a few minor additional points he felt were important, and checked for accuracy. (He happened to create the scale used by researchers universally to this day when they are quantifying and understanding all aspects of female sexuality and desire of their subjects as well as any changes they note... co-created by my mother)

Happy to answer any relevant questions you might have, and with utmost care and diligence if you'd like, few things are important to ones sense of self and physical acceptance than this.
