This is something that’s happened me twice now. Its definately not a coincidence.
Basically, after a night (and morning) of sex, at times where i was really aroused (strangely, this only happens to its full extent since my PFS with a “new partner” on a first or second encounter…strange!) i find that for the next few days i recover some libido.
Basically on these days i get spontaneous “semi’s” throughout the day and have sexual thoughts. This only happened me two or three times now. After 3 or 4 days i return to base. NB - otherwise i barely ever get spontaneous erections and even more rarely any real feeling of “surge” in my drive.
How i interpret this is that i get a surge of testosterone (or some other method that counters my estrogenic dominance) as a result. It never continues, obviously.
This definately isn’t a placebo or anything mental.
Anyone else find this? I think this alone is proof that SEX can increase test levels.
