I'm in a relationship with my boyfriend since 1 year 6 months and since nearly for 9 months we didn't have sex at all. He is the first guy with whom I lost my virginity and he also lost his virginity with me. He got a urinary tract infection (UTI) recently since just 1 week and he is blaming it on me so badly, it's definitely not from me I have that confidence because I'm very hygienic person, he is the first guy with whom I lost my virginity and it has been literally nearly 9 months we didn't have sex and he got his UTI just 1 week back. He is doubting on me and blaming on me, I'm just so stressed out and I'm even ready to take a test for his satisfaction to show the proof that it's not from me, but he is just making me feel so bad and he said he regrets having sex with me. He used so many hurtful words, I swear on God that UTI is definitely not from me but he is just being really very rude to me.
