I miss my boyfriend

I am currently at uni 2 hours away from my boyfriend so I can't just get up and see him. I am used to staying at his house pretty much every night and it's a big change and I'm recently missing not only him but obviously sexual intercorse. I wouldn't masterbate because I personally feel uncomfortable at the thought of doing so but I don't know what to do to keep me distracted until I can next see him. Or what wil stop me feeling a lust for him,can anyone reccomened like food or tea or something which will sort me out
