My boyfriend and I fool around of course, not all the time, maybe once a month. Farthest we have gone is He has fingered me and I have given him a bj. We makeout and all that, but we don’t have actual sex.

However, It has dawned on me I don’t really know a lot about std or sti. I always thought that as long as you were each other’s only partners you were fine. He is my first and I am his first and only. Neither of us have been tested bc neither of us have symptoms.

But here’s the question:

1.)can you get an std or sti in a monogamous relationship

2.) if I develop an std does that mean he’s cheating?

3.) how can I prevent std or sti

4.) what sort of std or sti can I get from non-intercourse sex
