Lovers and Friends part1

So one of my childhood friends Jason was on face book with his question of the day. He always ask relationship questions. I believe hes working on a project but hes being kinda secretive as to what.
Anyway the question was: "Is sexual fulfillment worth the risk of losing a friend or worse..wasting your time hoping they will be in a relationship with you" Basically he wants to know can adding benefits to your friendship cost you a friendship.
In my experience every time Ive done it I lost the friend. I had a friend I was close with from sixth grade thru high school graduation. After graduation we decided to take it to the next level and we were together all summer but it wasn't as serious to him as it was to me. It ended badly so badly I barely want to speak to him to this day when I see him.
The other time it happened was recently. Was also someone I knew from high school. We had an agreement to be bed buddies. I liked the agreement because his babymomma lived with him and since he was involved with her he wouldn't have to much time to focus on me.I had just came out of a relationship and wasn't looking for anything serious. We could just do what we came to do and part ways when it was over. Downside was I hate sexin in my apartment cause I don't like for em to know where I live. Rule#1 of the G code we fuck at your place and I go home but since he had someone living with him and I live alone my place it was.
Within 2 weeks he had done put her out of his spot. I'm having to throw this nigga out cause he wanna stay the night and cuddle and shit. Then he hits me with the I think I'm in love with you and I wanna see how far this can go. I'm like this what can go? He wasn't in love with me at all the sex was fire and he was in love with that. Me being me I need more than good sex to spark my interest in a relationship. I'm a Virgo it takes a lot for me to get emotionally attached to somebody. This nigga was callin me with his problems and shit and I was finding myself thinking "why does he think I care" Finally I said we should end this before someone gets hurt and by that someone I meant him cause I clearly saw it going nowhere. One of my friends later told me when they found out that I had messed with the guy that he acted as if his puppy died when I broke things off. Last I heard he has since moved in with his babymama at her new spot.
