PS: telling him about you going to an ST, is a double-edged sword.
On the one hand, it shows that you are really concerned about this area, and this is important to you.
On the other hand, if he is really hostile to the idea of counsellors... then he will view every new thing you try, as " a "trick from that therapist to try to get more sex out of him."
If you know that he is hostile to the idea of counselling in general, then I would personally suggest just going yourself, and specifically NOT telling him, at least initially.
