I’ve (f28) been with my bf (m43) for more than 3 years and our sex life has always been terrible. I’ve been quite active before but it’s just no fun with him and we tried a lot of different stuff already but it stayed bad. I miss it! But there is this one co-worker who just horns me up whenever I talk to him (we are just colleagues and nothing more than light flirting ever appeared). The only times I agree to have sex with my bf is when I was in contact with said co-worker before, otherwise I just don’t get into the right mood. It’s that cheating already or emotional cheating or whatever else?
