if you mean something you can read with little to no embarrassment try,
http://www.mangago.zone/read-manga/hanaya_no_nikai_de/ (goes as far as kissing, but implies more so you get the feel of yaoi, also great emotion and I loved it, you could try the other parts to, those are about Aki's brothers ^^)
http://www.mangago.zone/read-manga/aitsu_no_daihonmei/ (near the end of the updates [hasn't updated for a while] it gets into more in the beach scene that they get stranded on, but nothing to big)
http://www.mangago.zone/read-manga/neko_neko_honey/
http://www.mangago.zone/read-manga/hidamari_ga_kikoeru/ (I'd end at 12.7, since it seems to be continuing and if you don't like cliff hanger.... 12.7 is a good end till they update more)

I have more in my yoai list, but not all are 'safe' to read in public, but you can decide what best fit your needs:

Hey, I'm looking for a yaoi I can read during school at reading time in MSIP. I would love to find something to read because I want yaoi but I do have someone sitting behind me so it can't be that bad. I'm not picky about what it's about as long as it's really good.
