Suddenly attracted to men, pre-HRT?

Did anybody else also feel changes in their sexuality upon coming out as trans? Previously to coming out, I was primarily attracted to women. This still holds true, but even pre-HRT I can now also see myself pleasuring another man like f.ex giving a blowjob, or getting fucked by him.

This is quite surprising to me, considering that I'm still pre-HRT, but I'm welcoming it!
