<human>: Give me the gist of the text in a nutshell

Hey guys I'm posting from a throwaway since my bro is a redditor and reads my posts.

Basically my brother who is 15 and a sophmore has been stealing condoms from my desk drawer.

Our dad died in a car crash several years ago and our mom is great but I don't think this is her business and I don't really want to tell her. So I think it's my responsibility to have "the talk" with my brother and make sure he's being safe in addition to him getting his *own* rubbers.

I was his age when I lost my v card so I don't really care he's having sex, but IMO if you're too embarassed or too broke to buy condoms yourself, you're too immature to be having sex. Plus I'm really annoyed he's been coming into my room and stealing my things, even though I'm glad he's smart enough to know he should use condoms.

But still this is...awkward. But I do need to say SOMETHING. How do I even begin this conversation?
<bot>: Little brother has been stealing condoms from my desk. I'm the only male figure in his life. How do I start a conversation for "the talk" and about him getting his own protection?
