i have a bf and we been doing it for like 2 months
the first time was like one of the most painful thing i ever experienced
and then for a while after that it kinda hurt, and if it didn't i still didn't feel much
but i think im getting used to it (maybe just less in my head about stuff) because last 2 times felt nicer, and the mental 'oh this is sexy' aspect and getting to make ur partner happy is nice
but im still let down a little, i think im just not that sensitive, porn and ppl talking made me think it was gonna be mind blowing
