My boyfriend only cums when he's inside me

My boyfriend only agrees to deep cumshots in me, so he has to put a condom on. Even if I suck him off, he stops me, puts on a condom and cums as deep as he can in my pussy. The problem is that one day we didn't have a condom on and started kissing. I was too horny to stop him and let him come in me raw. I was worried, but it felt so good I couldn't say anything, and then I felt him pulsating inside me and a thick warmth spreading in my womb. I won't lie, it was the best sex I've ever had and I had an orgasm right after. Luckily it was a safe day, but now I'm afraid it might happen again
