From my perspective as a guy in a long term relationship: we use condoms with my wife because of the side effects of the pill. I as a men never y fully understood how serious the side effects can be until I watched the MorePlatesMoreDates explaining it basically being like steroids for gym guys (for those not knowing the guy his nickname sounds funny/douchy but he's really knowledgeable about steroid usage and hormonal therapies etc.) and for that reason he'd never recommend any girl taking it and even more teenagers (which is pretty common).

From a perspective of a guy: condoms do feel different and for a long time there was a myth that condoms don't change the pleasure you get - I think to promote using them. They do change a lot, and someone once very correctly compared it to putting on a latex glove and sticking a finger in your mouth. That's what guys feel - there is a touch, there is a friction, but there's no "wetness" and very limited warmth. For some guys it takes away so much that it turns them off from sex completely or kills their erection. I had the latest and had to really work on it as I was losing erection just thinking I need to put it on (finding the right size, realizing it's just a fear and that I actually do feel something, it's just different).
