Dear Besotted,
If you put funny Post-Its in her cubicle and deliver her favorite candy bar via inter-office mail, then no, you're not a prick. If you barrage her with emails, visits to her cube and subtle threats about telling the boss if she won't join you for an evening of French cinema, you're still not a prick. You're a white-collar stalker.
Office romances make people paranoid, and this paranoia causes them to apply a higher standard to prospective partners. There's "Hot," and then there's "Hot, but do I really want to take the risk?" Ninety-nine percent of folks are probably going to fall into the latter category. Including you. We also don't know if she's using the coworker thing as an excuse because she's not that into you, or if it's a genuine showstopper. For all intents and purposes, we're dealing with a long shot. Forgive me if this sounds calculated and grody, but you need to court this woman like you would a client. Conduct yourself with patience and class and go for the long, slow sell. Easy on the gold jewelry and aftershave, Besotted. When you go out for a drink after work (i.e., schmoozing with the client), see if you can get her to reveal the reasons why she wouldn't be into dating a guy from work. It's too obvious if you ask her outright, but more general questions, like, "Who was your first workplace crush? Mine was the girl at the pizza shop, blah blah…" and "What was your best/worst breakup?" will open the doors to her fears and reservations.
Then you use that information to inform your behavior (listen to me, all businessy and shit). If she's freaked by guys who are clingy, take your time returning those emails and calls. If she had an ex screw her over by spreading rumors, show her how good you are at keeping secrets, even if it's something stupid like stealing pens, or spilling by the coffee machine and not cleaning it up.
Barring that, the best thing you can do is just lay low, be the best possible version of yourself and continue to explore other romance options. This is a long shot, and your dick deserves a better shot than one ticket in a lotto.

Dear Daydreaming,
I want to help you, but I feel like we've got to clarify. Is it the experience of being queer that you miss, or the sex with other girls? I know it seems like they're inextricably linked, but does that necessarily have to be so? I'm fully aware that comparing heteros and gays to queers is apples and oranges, but does a heterosexual stop being a heterosexual if they're going through a dry spell or abstaining from sex? Is a gay guy not gay because he's a virgin? Most people would say no. Is there any way you could apply some of that mentality toward yourself?
A lot of people feel the urge to get the fuck out of Dodge right before they get the fuck out of Dodge or do something like cheating to express their discontent with the relationship. Nothing says "I'm feeling really fucked up and scared about this" like a little sabotage. You need to find healthier ways to sublimate, both sexual and non-sexual, including but not limited to: experimenting with role-playing and porn; continuing to share your feelings about this with your guy; and spending more time with your queer homies (but not if you're going to screw around with them. That defeats the purpose). A good shrink and a little pharmacology could help, too, but I pretty much recommend that for everybody. Also Glide dental floss. That stuff is a fucking miracle, I tell you.
So what if this queer yen continues to grow stronger? Well, then you may want to break up or talk to your boyfriend about negotiating some sort of "open relationship lite" — a kinder, gentler version of the free-for-all fuckfest that most poly-averse individuals falsely imagine an open relationship to be. I realize he's against it now, but he may change his mind once he realizes that cheating and/or breaking up are becoming more and more realistic alternatives. He could still say no and that's his right, but at least he'll know — and you'll know that you two considered all the options.  n°
