Hi, Melissa, 
I noticed this is your first post, so welcome to Worthy. And you came back to check for a response to your questions last Friday, but no one had seen or answered it yet. I do hope you'll return to see what other posts are now being submitted. I'm not sure I can answer them exactly, but do have some knowledge of this occurring in some church services I've attended in my past. Allow me to explain.  
I highlighted the main feature of your experience, and it indicates you're not the only person who also has this happen to them. In some Holy Spirit filled churches, this is commonly known as being "slain in the Spirit". And all these sensations when you go forward in worship, or have the pastor pray for you are quite common, so don't be overly concerned. You expressed it was a "beautiful feeling" so, I'm assured it is. 
Often when this happens in churches such as these, there are elders in back of those being prayed for, and they will catch your fall, and see you safely to the floor in front of the pulpit. For modesty's purposes, they will also drape a cloth over the lower half of your torso. It's a really nice gesture for women, especially when they are wearing dresses. I'm wondering if the elders of your church are doing this for you.
The allowance for you to remain there for as long as you desire is also usually given during this time you're in prayer. Elders in attendance are helpful in assisting you back on your feet again, and see that you are able to return back to your seat in the pews. If not, they should be. This is only common courtesy, and I've seen it numerous times. Otherwise, it would seem to be a more uncontrolled and chaotic occurrence. 
Now, the other sensations of heat on the back of your neck and forehead, I've not heard any other congregant express this publically. Perhaps there could be some sort of healing going on in the inwardness of your body and soul. I'm curious how many times this has occurred, as it was stated this happens everytime you go forward in worship and/or personal prayer. I wouldn't worry, this is also known as a "soulish experience". 
God bless you!
Shalom,

P.S.  The overall feeling of body warmth during this time is not a an uncommon experience, however. I hope this answers some of your questions.    

A few things to consider that weren't mentioned in your post, Faith. If you feel a need for parental consent, or their blessing in other words, it gives me the impression that you might be either very young, or your parents are very controlling concerning getting married in general. Could this be the case, in either possibilities? I would also hope for the two of you to be equally yoked, spiritually, morally, and with general compatibility as a prospective couple. That being, is he born again as you are, and do the two of you see similar beliefs, doctrinally speaking? Just curious. God bless. 
Shalom,

Hi Justin, 
Looking at your post, and my there's so many questions! So, you have some concerns about where you might spend eternity, and this is a good starting place. Wish I could answer them to your satisfaction, but am in hopes that seeking will result in finding Christ as your Saviour. Keep searching. Attend church with your mom, and get into some fellowship with the college age there, if this is possible.
Get a bible translation that is easy enough for your understanding, and read it. I would recommend the New Testament first. Then the doubts will melt away, and into some faith that you're in desperate need of. God bless you, Justin. Keep posting. Just a couple more, and be welcomed to Worthy. Hang in there, Jesus wants to fulfill your life. Let Him do that. Know that you're in my prayers. 
Shalom, 
David/BeauJangles
