Hey I'm really confused and worried.

I'm 21, I masturbate roughly once a day but I don't usually bother with penetration because I don't think its as good as clitoris stimulation, but I bought this new vibrator after my old one broke and decided to test it out, and ended up penetrating myself with it (since it's new and all), and noticed a totally different discharge to normal. It's white, odorless, and I guess it looks similar to cottage cheese... and feels kind of dry if that makes sense. (Almost like clumps of dry skin if it was wet.) This is not at all like the stuff that I usually get coming out which is either clear or white, depending on the time of the month.

I consider myself generally quite healthy, as in I have a good immune system, hardly ever get ill, recommended weight for my height... although I do live a very student life style, as in a diet mainly consisting of junk food, fizzy drinks and beer, I don't do a lot of exercise and usually have a very irregular sleeping pattern. I also often feel stressed from workload... but I do have very good hygiene (shower at least once a day and always wash down there), and haven't had sex in over a year... and by sex I mean, I'm a lesbian, sex to me generally consists of fingering, toys, and 69ing anyway. I've never had sex with a guy, so I think it seems pretty unlikely that it would be an std. I've looked up what it could mean and the only thing that came back was a yeast infection, but every source also said that yeast infections are itchy and inflamed and I'm not itchy or inflamed at all. I'm not in any discomfort and I look totally normal down there.

So anyway, I'm trying not to panic, but this is weird. What should I do? Has this happen to anyone else? Is it normal? Is it maybe to do with not being used to penetration, or could it be something bad... any advice would be extremely appreciated. (I could do with some comforting too!) :-(
