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

First off let me explain the girl. I've had my eye on her for over a year now, have been establishing a good friendship/relationship, and let her know how I felt (awful timing though since she left the country for school soon after) but she didn't want to commit to anything while she was gone (reasonable). She'll be back next semester, but is leaving again the following semester...great, right?...but over the past few months while she's been away, we've been keeping in touch really well through text and Skype nearly everyday. We've talked about where things might go and if she thinks she'd be interested in dating when she got back, but she's yet to give me a solid answer to "should I wait or not?"
The real conflict comes in within these last couple of weeks. The girl (we'll call her Jess) that I hooked up with two years ago and haven't spoken with since, texts me out of nowhere and is down to spend some quality time learning my anatomy. I told her that might be worth organizing, so my near future might be eventful. THEN, this past weekend a friend of mine and her smoking hot best friend put me on the spot about a casual threesome...I was unprepared due to my lack of experience with sex or girls for that matter (I've been single for pretty much my whole life and had sex once which was with Jess) so I bolted asap to get out of me embarrassing myself more than need be. Good news is, the offer is still on the table somehow.
<bot>: Would it be bad if I were to get with these 3 girls since I don't have a solid answer from the one I really want and probably won't have one for 5 months?
