I mainly play femshep in Me trilogy, but I have played maleshep as a no romance trilogy run which I found to be one of the best plays of the trilogy.
I played him as romancing Ash but chose to save the diversion team vs the bomb and Ash was who I left with the bomb. So I role-played maleshep as someone who never got over losing Ash even if they never consummated their relationship.
I am not a big Liara fan so i find the Romance options for Femshep who I play the most limiting as a straight male gamer playing a female protagonist. So I have done a few no romance playthroughs with Femshep as I get tired of the same romances.
I like that. Poor Shep, her death would have been driving him on, not caring if he died because he'd already lost the woman he loved. The drama! I had no romance in ME1 in my Tali run and I didn't miss it at all. But I am soppy so give me a LI option in ME2 and 3 and I'll take it.
I can imagine the options are pretty bad for you as femShep, at least Garrus can be your bro, but other than that they pretty much suck if you're not a Liara fan. I hope to goodness they give femRyder some better options this time round.
Btw, a straight male gamer mainly playing femShep? Well Sir, you're now one of my favourite ppl. 
The amount of guys who can't play girls and seem to think a male protagonist is the only option gets old real quick.
