my bf have been so persistent in sucking my breast too during our intimate moments. i do allow him to do so especially so that i am not allowing him to have penetration on me. i am a virgin. but after few days, i feel my breast have been hurting. and obviously sinse weve been doing this lots of times already, i feel an increase of my breast size.. super slight though that i cant tell if it is really the cause
You should let him suck your nipples! during sexual activity nothing can happen. You only get HUGE npple when pregnant and its would go away but you should not stop him!
Having your breasts sucked during sexual activity cannot do anything to promote breast growth or make nipples big, unless possibly the sucking was so vigorous and prolonged that it had the same effect as certain suction devices which are claimed to promote breast development.........
