Need relationship advice

My bf (Sam, for the purpose of this post) and I have been together for over 2 years now, and it's been wonderful so far. However, I've noticed some things in the last few months that have bothered me.We met each other on A4A, and he kept his account after we got into a relationship. I've asked him about it and he says that there are friends be talks to on there. I left it at that and called it good. Quite recently, though, I found out that he downloaded Tinder on his phone.Now, our sex life isn't great, admittedly. I work 40 hours a week, and the bf's home alone while I work. He travels for his profession, and he stays with me when he's in town. I don't often feel in the mood after work, but more importantly, there's the issue that I don't like giving or receiving anal. It's mostly because I was in an abusive relationship where the guy would coerce me into anal sex, even when I wasn't in the mood.Sam and I talked recently, and he expressed that penetrative sex is important to him because it gives him a different (and better) release over just fooling around. I get it, but I'm worried that this may turn into a dealbreaker if things keep going the way they are.So, does anyone have any advice? I love this man with all my heart, but I don't want him to resent me for not being comfortable with penetrative sex.
