Sounds like you are trying to figure things out for yourself and feelings you have about tickling and intimacy. The tickling community, like any group or subgroup of people with specific preferences for some activity, is a very broad community. What any one of us who enjoy tickling like regarding relationships and intimacy covers the spectrum like any human activity. You could substitute "tickling" in your questions with "spanking" or "fellatio" or any other activity between consenting adults.
"Normal Sex" is a very relative term. If by normal, I assume you mean male-female intercourse. Sounds like you are asking if those of us into tickling can enjoy sex without tickling. Some can, come can't. There is no right or wrong answer.
Similarly, concerning sharing a love of tickling with your partner, some do, some don't. For those that do, the when and how is also as wide and different as there are people in the world.
As for experiences in general, you are in the right place to stroll through this online forum where you will find every variety of experience regarding tickling and relationships and sex.
Anything I, or anyone else on TMF, respond to your questions, only applies to me.
So, for me, with a lifelong tickling preference, fetish, desire, passion - whatever you want to call it - and I'm 74, and was aware of my tickling inclinations before I was 21, my answers are:
-Yes, I enjoy sex without tickling. That's me, not anyone else.
-Yes, I've shared my tickle desires with all my intimate partners. I'm a m/f ler by the way.
-When and how I have shared with my partners has entirely depended on the other person and our relationship. For me, even with those I've met online, including brief one-time encounters, the relationship between myself and the other person came first, tickle stuff after. This includes vanilla folks and those more into tickling than myself.
-How do I treat my tickling desires? Like I treat anything else in my life. It's just part of me. I try to make sure I control it, and it doesn't control me.
You'll figure it out. With intimate activity, if there is any generalization, I'd suggest being always aware how the other person is feeling as well as your own feelings.
