bull refused the condom mid-play and i panicked

horrible to type this. hotbull weve been seeing for about 6 months in sydney, husband watches, weve always used protection. last meet, twenty minutes in, i feel something off and look down and the condom is gone. ask him where it went and he goes "it came off ages ago, you didnt say anything so i carried on". my husband was in the en suite. i froze. completely froze. didnt say stop didnt push him off just lay there till he finished. as soon as he left i sobbed in the shower for an hour. husband is furious at him but also a bit at me for not shouting. ive been on the pap and tests since. how do i not feel like i let myself down. 39 hes 42 bulls about 36
