Weird behaviour of hubby. Normal.

I hav been married for last 1 n half yr. I m having Normal sex life. My husband likes to watch lesbian videos.frm starting of marriage life I m observing this thing. He just like to watch lesbian videos. many time I checked his mobile history. 90% of pron videos r of lesbian.bfor sex also he watches lesbian videos n comes to me. For 1st 3-4 months v never had proper sexual intercourse also.he never used condoms n use to say tht v don't want kids n use to stop strokes in middle. But now atleast v r having Normal sex life. But I m fedup of his behavior of watching lesbian videos. My Frnd said tht it's his fantasy.n he does for entertainment n sexual arousal.she teases me tht he wants me to do lesbian sex or Threesome sex. But I m sacred now. I can't talk with him. do he really wants me to do lesbian sex. Why he need to c lesbian videos bfor r sex. Wht kind of fantasy is this.is his behavior normal.
