my experience is this.
long ago when i try fucking first FL. everything was kinda rushed and I was too anxious if might kena anything end up cannot even get hard. Had to capped bj / hj to shoot.
After that I realise that I'm not into fucking female strangers. Instead, I will get my fuck from my usual gf turned ex-gf/fwb.
Before each fuck with my fwb, I will got for a super hot and teasing massage to wake up kkj first and find fwb. Always works.
If I cannot tahan massage, then just ask for hj to clear it off.
