thoughts

please tell me when a person is unmarried, he/she will have sexual thoughts and feelings is natural. im so worried about all things. Is it natural that we think that one day we would have  a wife. and we will put bangel in her arm etc etc. Thinking about foreplay is natural and can we think about sexual Intercousre, when we are not married. I mean we would think as general (coz fantisizing is haram about any opposite sex until we are married). can we talk about sex with same sex obviously. Tell me all the Halal things we may think, when we are unmarried in the matter of sex. I'm so confused about sexual feelings and thoughts when we are not married-Halal and Haram in it. Also exploring your own body is halal.

I think of death all the time and it really scares me. These thoughts are really disturbing me. Please help!
