Initially I also incredibly hard time reaching orgasm. After the Doc added 0.5mg cabergoline twice weekly it became much easier - still a little difficult but obtainable, with some effort.
I am now on 0.5ml T twice weekly for 20-weeks. Initially at 0.4ml but Doc upped it a few months back. Also took 0.5mg anastrozole once weekly but due to sore nipples the Doc upped it to 1mg weekly. Based on this thread I think that I'll drop it back to 0.5mg weekly and see what happens I "might" even try zero anastrozole.
