I'm in the first serious LTR of my life, nearly 3 decades. Normally sex for me is with a condom and probably once a week. With my GF who is on birth control now it's quite often and no condom.

If men experience estrogen from the expectation of becoming a father could this type of sex be why my LTR is turning me soft? I do experience fear that blowing my load in her all the time is going to lead to pregnancy even though she takes the pill religiously.

What are some of your experiences in LTR and sex? Should I just cut the sex down to a couple times a week and finish in her differently most of the time? I just don't like how I'm becoming even though this LTR is the best shit ever.
