Sex toys

So me & my boyfriend have been going through some things I found out he cheated on me 4 months ago & I gave him another chance for the simple fact we wasn’t taking eachother serious 4 months ago, I never had sex with anyone but him & today we had sex and he said I smelled like lubricant I smelled myself and agreed not knowing he was thinking I had sex with someone with a condom for get back , I honesty have not had sex with someone since I been with him however I use my toy from time to time because he live in a different city and we only have sex on weekends , is it possible for the toy to make me smell like lubrications or condoms ?
