<human>: So this is probably going to be a bit confusing but bear with me please. I met this guy, let's call him Michael last year in one of my high school classes. We were casual friends for a few months but I got switched out of the class and only talked to him occasionally after that. We're both part of our school's LGBT club and he told me he was bisexual and I told him that was cool, so was I, and that was the only time we ever really talked about sexuality. 

Now I'm a pretty open person, I'm friends with lots of LGBT people, helped one of my friends transition from FTM and I'm very supportive of all my friends and exploring their sexuality.

Now, onto the Michael problem. He texted me out of the blue a couple days ago and after a few minutes of small talk told me that he'd been exploring wearing women's clothing. I'm cool with that and I'm ok with being his safe place to talk about this and not be judged, but now he wants me to come with him and/or tell him how he looks and give him advice. I'm not super comfortable with this, I don't know him that well and I just don't really want to see him in the women's clothing even though I'm supportive. 

So my question is, how do I tell him I'm fine with talking to him and helping out but I don't really want to see him in it or help him pick stuff out? Thanks guys!

Provide a brief overview of the text.
<bot>: An old casual friend has decided he's into cross-dressing and wants me to give him advice on how he looks in it and stuff, I feel awkward but want to be supportive. What should I say?
