Search Results: spice it up

So her and i are both 16, her boyfriend is 17. they’ve been dating for about 4 months now and kinda wanted to spice things up. I’ve never had sex, but they’re looking for another girl to have a “threesome” with. the other girl wouldn’t actually be having sex with the guy, just doing other stuff ya know? anyways they asked me if i’d be up for it and i think it would be kinda fun but i don’t want to ruin my friendship with either of them, my best friend can also get jealous but she insisted she really wanted to do this. anybody been in a similar situation? i need advice. i’d be comfortable doing it i just don’t want to ruin my friendship with my bff. i feel like it’d also be awkward. I don't know

I'm 20 and my boyfriend is 21. We have dated for 7 months now but before we dated we knew each other for a year. When I'm with him, everything is so simple. Talking about anything and everything is always so fun, even when it is just about our day. We know each other very well now, we are completely unmasked, and I always feel at home with him. He's the first person that I've ever felt this clingy towards. He is one of few I have fun with hanging out one-on-one.
But it's finals week. I'm used to seeing him for a couple hours every day, but sometimes he has to study for an exam for a day or two. Whenever this happens, I get really lonely. My roommate also moved out so I'm in a room by myself. I have a friend group, but we don't hang out individually because we click better as a group, and some members are living off-campus so we can't get together every night like we used to. It takes a very special person for me to like hanging out with them one-on-one since I do much better in groups, and because of that, when he leaves I don't have much to do.
The hobbies I tried to develop fell through (making bracelets--I broke the needle. Got frustrated as hell) and clubs on campus seem more interested in spicing up resumes rather than actually doing stuff. I'm a little different, so are my friends, so it's hard to find someone for me to really enjoy being around.
So I'll sit in my dorm, watch YouTube and I'll feel guilty for wasting the day away. I get great grades and everything, I work out and try to eat healthily, but I guess I want to know-what are fun, cheap, productive things to do by yourself? I hate to burden him. Is it unhealthy how much I cling onto him? Is it weird I have issues with one-on-one relationships?
