Issues in my sex life😕

Madison

So for the last half of the heat my boyfriend has this thing where he will avoid a conversation about going down on me...it really bothers me because I think that I can pleasure him I deserve to be too, right? I ask him why and he just starts talking about something else...and that really puts me down. I feel like I’ve done something, but he all of a sudden just stopped doing it. What should I do? I’m at a loss now...
