How do I Ask a Friend to Set Me Up with one of her Boyfriend's Friends?

Hi, please give me your insight and advice on this. I am currently at university, on a medical/health related course and live in accommodation with other students on medical/health related courses. I have found it difficult to find a boyfriend as it is difficult to meet people as I am in a flat full of girls. The accommodation consists mainly of girls so it is difficult to meet any guys - and most of the guys in our accommodation are quite young and I am attracted to guys that are older as in my opinion they are more mature. There are also not many men on my work placements that are in my age range - so it is difficult to meet men that I could potentially have a relationship with. My friend has a boyfriend who she met on a dating site - she is 19, he is 25. He did Computer Science at university and he is really nice and mature and treats her well. He is really my type and I would ideally like to go out with somebody like him. He came round our flat the other week to see my friend but I don't see him that often. He takes my friend to gigs, they go out a lot and have had a holiday together. He's a really nice guy and I'm hoping he has a friend who is similar for me! I want to ask her if her boyfriend has a single friend in my age range that I could go out with as I find it hard to meet guys. The thing is I don't know how to ask as I am embarrassed! How do you think I should go about this and ask her without sounding weird? How does matchmaking in general work? Do any of you have experience with matchmaking and being set up/setting someone up? Please can you give me some advice? Thank you for reading and your insight and advice would be very much appreciated. :)
