Yogurt isn't helpful for yeast issues in the genital area. It's only helpful for bowel issues and then only if there is enough active cultures in it and you eat enough of it.
constantly messing with your penis will only irritate it more. Only inspect it once daily after your shower. No reason to look at it more often than that. When you masturbate, be sure to use a decent lube too so that you aren't further irritating things.
wrinkles aren't a std. continue to follow up on this with your provider to try to figure out what is going on.

Thankyou for your response, it does seem to get better when I leave it alone but it still doesn't look right. I do have a clear discharge after sex that is very sticky, I don't know what that may be. I haven't had any real problems besides the wrinkles. There is a little extra skin on the glans area that looks to be a little raised up but no pimple like spot or anything cauliflower like. Like I said the meatus looks to have extra skin as well. I am going to see a urologist when I can get the money to do so.
The wrinkles could even just be irritation or dry skin.
You've covered the common std's now with testing. see your regular provider or go to a low cost clinic to get evaluated for other things.
