I'm sorry but I don't like the amount of romance options I see so far as a Straight dude. Cassandra is.... not what I would consider attractive(in all aspects). I don't mean to say she is the worst romance option to who ever likes her but she's not my cup of tea. I wanted to hook up with Sera but she's a lesbian. I don't want to offend anyone it's just I want more options than this. Does anyone else have a problem with the current options in Inquisition?
No problems here (yes, even as a straight man - shocking, I know), and I'm sure, with the way Bioware writes characters and stories, that even the characters that I'm not incredibly excited for now will eventually grow on me, and my Inquisitor.
If you give the LIs a chance, I think you'll be surprised. As far as Cass is concerned, we shall have to agree to disagree. 
But you'll probably still put your penis in the cake anyway, because why not?
*joking* That is an odd thing to do to a cake... *end joking*
