Sexual Rejection ..

Hey y’all,

So my fiancé and I have been together for 4 years, engaged a month ago + two kids aged 3 and 6 months. We’re young, 20 and 23, and our sex life has always been good! Here recently though, he has been rejecting me a lot .. 95% of the time I’m the one initiating sex, which I enjoy. He does work 10-12 hour shifts 5 days a week from 2am-12/2pm so he’s tired very often. Something that I hate he does is though out the day he’ll be touching and rubbing on me, telling me nasty things he wants to do to me but come night time it all goes out the window .. Another thing, if I’m on my period or if we just haven’t had sex in a while he’s ask for head, I’ll give it to him but sometimes I just don’t feel like it and he’ll get the biggest attitude and start acting weird but when it’s the other way around I’m expected to deal with it. The rejection really hurts my self esteem and always makes me feel some type of way .. it makes me not even want to initiate sex or eliminate sex all together ..
